Tamil Nadu Reservation Paradox

[G.Subramaniam]

Tamil Nadu has a 69% reservation and is prospering
On the face of it, it looks like reservations are good for society

Let us start digging deeper

In Tamil Nadu, several upper castes that normally would be considered dwija in
north India are classified as Shudras or OBC

Banias - Chettiars are OBC
kayasthas - kanakku pillai ( counting pillai ) are OBC
Vellalas - Rich super landlords ( thakur type ) are OBC
Naickers - Descendants of Vijayanagar soldiers are OBC
Reddiars - Reddy migrants in tamil nadu ( landlords ) are OBC

In short the entire Dwija segment , minus brahmins is OBC

Much of this is due to historical stupidity of tamil brahmins
They were very reluctant to hand out dwija certification
For example, in Andhra, the Komati Chetty ( bania ) is a dwija,
whereas in Tamil Nadu, the Chettiar was not granted dwija and is an OBC

P.Chidambaram for example is an OBC

I am going to call this segment - OBC-Dwija or Dwijas masquerading as OBC

The net result is that in Tamil Nadu, the only Dwijas are brahmins,
Meaning in Tamil Nadu, the Dwijas are less than 3% of the population vs 25% in north India

In tamil nadu, the OBC-Dwijas have a 30% reservation
in addition they can compete in the open seats and possibly get 15% out of the 31% open seats

So 31% open seats are gotten by brahmins and OBC-Dwijas
30% OBC seats are gotten by OBC-Dwijas

Real OBC are called MBC ( most backward castes ) yadavas etc
They get 20%
Dalits get 18%, ST gets 1%

So

Dwijas -
Tamil Nadu - 61%, All India 50%

OBC -
Tamil Nadu - 20%, All India 27%

Dalits
Tamil Nadu - 18%, All India 16%

ST
Tamil Nadu - 1%, All India 7%

As you can see , Tamil Nadu is over-represented in Dwijas and is run by a higher average IQ group than the rest of India and no surprise it is doing well

Of course by not driving out the tamil brahmin they could do even better

[G.Subramaniam]

In Maharashtra too, the non-brahmin dwijas did a lot of anti-brahmin activism

Shiv Sena Bal Thakeray's father did a lot of anti-brahmin activism because he felt that brahmins were getting too many jobs

Thakeray is a Prabhu, a Kayastha

But kayasthas were Dwijas

Whereas in tamil nadu, a Velala being a non-dwija could rally the real OBC, ( MBC ) and Dalits behind them in an anti-brahmin crusade

[G.Subramaniam]

The DMK is a party of Chettiars and Vellalas
banias and landlords

The PMK is a party of Vanniars ( MBC )

The MDMK is a party of Vijanayagar descendants

The Chettiars and Vellalas were historically literate, forward castes
they run several mutts and had a rich heritage in tamil literature
and were in no way backward

In Sri Lanka, the velalas took to english medium education
In tamil nadu, they lagged behind in english medium education resulting in brahmins filling the vacuum
Instead of taking the hard way to learn english, it is much easier to whip up hatred against a 3% minority , fool the real MBC and Dalits and grab power

[G.Subramaniam]

In Maharashtra too, the dominant Maratha caste ran an anti-brahmin campaign and got themselves declared backward
Just as Jats got themselves declared backward

In maharashtra, the racket is like this
Marathas have 2 castes,
Upper caste Deshmukh and lower caste kunbi

Marathas declare themselves kunbi for reservation purposes and
Deshmukh in matrimonial columns

[G.Subramaniam]

When I went to Engineering college in 1975,
the open category was 50%.

The entrance criterion was gerrymandered to limit brahmins to 20%

The cut off for brahmins was 95% in math-physics-chemistry
the cut off for non-brahmins was 90% in math-physics-chemistry

Out of the 80% non-brahmins, 50% were OBC-Dwijas, 30% were MBC and 20% SC

In academic performance, the OBC-Dwijas did as well as the brahmins
The MBC did somewhat worse , but passed
The SC mostly did not pass and repeated several years

Smart trick

[Guest]

This is exactly what I was wondering.

At 70% reservation in the society which is maybe 20% 'backward' the 'benefits' and the opportunity costs should decrease - except for the few who will fall by the wayside.

The other aspect of this is that this should result in suboptimal allocation of resources (if limited) while at the same time suboptimal realization of payoffs.

My suspicion is that both of these must hold true for the TN society. What would be the best way to prove this ?

[G.Subramaniam]

Now I am going to get politically incorrect
and talk about IQ and heredity

----

I read a recent article on the high IQ of jews

Per this article, in the middle ages, for a few centuries, jews were restricted to only a few jobs, such as banker, diplomat etc
This being the case, the jews who were talented as bankers, diplomats,
in short, the higher IQ jews produced a lot of children, whereas the jews who were not high IQ produced fewer children and died out
In a sort of Darwinian evolutionary selection, the surviving jews evolved into higher IQ. Each generation, the non-superior IQ jews slowly produced fewer surviving children
--

Now I am going to take this hypothesis, 1 step forward, this genetic darwinian pressure has been operating for several thousand years in hindu castes
In each caste the Darwinian selector is slightly different and based on the occupation. Different kinds of skill sets become darwinically pre-selected in different castes

If you were a bania and were poor in accounting skills you went extinct
If you were a artisan caste and you were not a skilled artisan you went extinct
If you were a brahmin and could not memorise huge texts you went extinct and so on

The caste system in short is a mini-evolutionary lab

--

If you look at US contests such as spelling bee, national geographic bee etc
, Indian children, more specifically UPPER caste hindu children excel
--

IQ has a norm of 100 with a standard deviation of 15

Based on complex statistical analysis of the gerrymandering in admissions in Tamil Nadu, circa 1975

I am going to make the following assumptions for mean IQ
Brahmins = 115
Dwijas = 108
OBC = 98
SC/ST = 90

all bell shaped overlapping curves
Meaning many SC/ST will outscore many brahmins

---

What this means is that if reservations are held solely on the basis of
poverty, brahmins and dwijas willl get most of the spots and that is why there is much opposition to this from rich OBCs

---


I also want to add a caveat,
Islam seems to pull down IQ by 20 points

In UK, the IQ rankings are
1. Hindus
2. Whites
3. Afro caribeans
4. Muslims

Compare Arun Jaitly and P.Chidambaram
They look alike,
Jaitly is forward caste, P.Chidambaram is OBC

The brighter , higher IQ tamil brahmins have moved elsewhere
Many tamil brahmins have also moved into business and are prospering as
factory owners while the dravidianists are fighting over crumbs such as jobs in the factory

[G.Subramaniam]

Moving onto kerala

Until recently, Nairs were classified as Shudras
In kerala, which had a matrilineal system, in many castes, many women had serial husbands and in many cases these husbands were Nambudiri brahmins

What this meant is that thanks to cross breeding for 1000 years , all the castes between Nair and Nambudiri - look like nambudiris and it is not so easy to incite anti-brahminism in kerala

GS

I think the counter argument is as follows --> Lets assume that all brahmins have IQ 140 and above. For a healthy economy show that having a person of IQ 120 doing a job with a job reqt of IQ 100 is bad.

IOW if brahmins of say 130 are replaced by an OBC of IQ 120 for a job with 120 reqt while the brahmin does a job with reqt of 100 then is it bad ?

----------

We need several pieces of data to make any headway in this. If somebody can post some links where we can find the relevant info that would be good. I think the foll pieces of data would be good to start with..

1. 10+2 median scores by caste
2. univ enrollment scores by caste
3. univ enrollment cutoff by caste
4. prob of a person getting admission for a given degree by caste.

To repeat the hypothesis in question is -> if you reserve large portions of seats by caste then it induces enough competition so that both the benefits/costs due to reservations become irrelevant. The grey area is the kind of economy involved --> TN might not exactly be the kind of knowledge economy like bay area for eg.

What is happening is inefficient use of resources
Are parsis an asset - yes
Could India get along without the parsis - yes again
Would India be better with the parsis- yes

In Uganda, with an average IQ of 75, Idi Amin kicked out the 100 IQ Indians and
yes Uganda survived and now Uganda has invited them back

What is happening in tamil nadu and other parts of India is lack of vision
In Singapore, Lee Kuan Yew gives money to get high IQ women to breed more
In US, IQ tests for employment are banned,
In India, microsoft uses IQ tests for hiring staff
I cant find the quote, but per Bill Gates, all he cares about is hiring the smartest
staff

To play devils advocate, I think a small amount of reservations is good,
even for upper castes
What reservations do is to darwinically winnow out the lesser talented among the upper castes.  The over-achievers still get through despite reservations
However, beyond a point , even the over-achievers get winnowed out

It is bad for hinduism because with the brahmin evicted, the field is open for the

Also keep in mind, there is a very short step from anti-brahmin to anti-hindu

The tamil brahmin caste has split into 2, one path leading to higher IQ and the other path to extinction
The more talented have become marwari type businessmen or gone abroad
I was surprised but IQ gives flexibility and can be redirected to other fields
The less talented and temple priests are going extinct

Many of the dravidianists have a taste for brahmin women
Periyar asked his followers to rape brahmin women
Most of the DMK leadership have brahmin concubines
Some of the poorer brahmin women are marrying OBC-Dwija men

Why did retribution take so much longer to reach north India? "In the south, caste battles were polarised between Brahmins and non-Brahmins," said Sheth. "In north India, not only were Brahmins more numerous, but there were also other upper castes with whom they could ally."

--
In north India, brahmins handed out Dwija status to many castes
whereas this was not done in south India
-----

Periyar raised the banner of backward caste revolt in Tamil Nadu. "The castes which backed Periyar were hardly the wretched of the earth," said Gupta. "They were rich, powerful castes, unwilling to stomach Brahmin superiority."

When the DMK, an offshoot of Periyar's Dravida Kazagham (DK), won power in 1967, the writing for Brahmins was on the wall. "Once the DMK took charge it embarked on a severe and systematic programme of reverse discrimination," said Sheth. "Reservation quotas were raised to such high levels that Brahmins were squeezed out of government-owned educational institutions and jobs."

On the taste of dravidianists for brahmin women
==


It is not only ironic but hilarious that some of these very Dravidian leaders - who had opposed Periyar's marriage- would later go on to set up ‘Chinna Veddus' (second houses) throughout the state. Some times the occupants of these ‘Chinna Veddus’ were none other than Brahmins.


---

The late MGR – a Menon from Kerala - would be the undisputed and most popular leader of the Dravidian people for almost a decade until his death in 1987. His wife came from a Brahmin Family from Varkala in Kerala. His inner circle mainly consisted of Malayalaee Brahmins. His concubines mostly belonged to the Brahmin caste.

It is an open secret that MGR , who had promised to marry one of his young Brahmin mistresses at a famous temple located on a hilltop backed out at the last minute due to his fledging political career- though Periyar ruined his political career by his marriage, he was gentlemen enough to keep up his promise to Mani Ammai

We Are Like The Jews'

'We Are Like The Jews'

Politics apart, Brahmin-bashing is rampant in literary and cultural
worlds too

ASHOKAMITRAN


The acclaimed Tamil writer opens his heart to S. Anand on the
experience of being a Brahmin in Tamil Nadu.

For the Tamil Brahmins, it has been one century of being on the
defensive. The community feels castrated. The Brahmins have never
anyway been the placard-holding type; they have rarely expressed their
feelings openly. The Tamil Brahmins have been used to taking insults.
Hence perhaps the lack of visible protests or reactions. Theirs is a
guilt-ridden existence, their spirit has been killed by a negative
self-perception… They have been driven to a quiescent state. Their
situation is very similar to that of the Jews in the 1930s.

With the anti-Brahmin movement dictating the terms, the urban Brahmins
began to eschew ethnic markers that revealed their identity. They gave
up the kudumi (tuft), began to sport moustaches like non-Brahmins,
changed the manner in which they spoke Tamil, changed their attire,
some even began to eat meat… they did everything so that they are not
identified as Brahmins in the public sphere. These were all modes of
defence, strategies for survival.

Today, few Brahmins speak the brahminical dialect. Despite all these
camouflages, even today 50 percent of the Brahmins stand out in a
Dravidian setup. One can easily mark them out physically! They are so
obvious! Over the years, it has been fed into their psyche that they
are different from the Dravidians. The Dravidian movement always
called them vandherigal (immigrants/ outsiders)… Even in non-Vedic
classical texts, there's an injunction to safeguard and feed the
Brahmins.

The Sangam epic Silappadikaram was written by a Jain monk, Ilango
Adigal. When a wronged Kannagi ordains the burning of Madura, she
says: 'Let the city burn except the Brahmins and cows.' Even the Jaina
author showed high regard for the Brahmins. But the last 50 years have
been very tough. The Brahmins gave up on government jobs, and in
whatever they did have had to work harder to prove themselves. Natural
discipline and thrift are brahminic qualities that have survived. If a
nonbrahmin has a windfall he just spends it on meat and drink. The
Brahmin always saves for the rainy day.

Though not a follower of the math, I had some regard for the earlier
pontiff. In 1951, my mother was widowed. In 1954, Periyaval
(Chandrashekarendra Saraswati) had camped in Chennai's T.Nagar area as
part of chaturmasya. It was a time when M.S. Subbulakshmi sang for the
first time in the presence of Chandrashekarendra Saraswati, but at
that point he ignored her and Sadasivam too. My mother repeatedly
visited the Acharya on an empty stomach at his T. Nagar camp, but he
never blessed her with the holy water since she was an unshaven widow.
I never had much interest even in Chandrashekarendra Saraswati. The
last I saw him was when my son and I attended the centenary
celebrations of Periyaval (Chandrashekarendra Saraswati). He was a
merely an exhibit on the occasion. It was humiliating to the
Paramacharya.

After Jayendra Saraswati took over, I never visited the math. Jayendra
Saraswati has been silly at times, making loose remarks and courting
controversy. But when his arrest happened, I personally felt very
shocked. Now, I'm indifferent. There must have been something murky in
the Kanchi math. But the manner in which the case has been treated
makes us feel that there is indeed persecution. Irrespective of a
Brahmin's faith or belief in the Kanchi math, the arrest of the
Shankaracharyas and the manner in which the case is being dealt with
is a humiliation for the entire community. The only sign of hope after
the Shankaracharya's arrest is that several women have come out in
protest.

This is encouraging and extraordinary for the community.

Brahmin-bashing is not confined to politics. It is a pastime of the
cultural and literary worlds as well. Even the Tamil film industry
merely caricatures the Brahmin. It is a totally non-brahminised public
sphere that Tamil cinema depicts. It is very difficult for a Brahmin
to get a foothold in the film industry today—as an actor, assistant
director or lyric writer. Earlier, when Brahmins played a significant
role in establishing the film industry, the world of cinema had a
neutrality, but today an obviously non-Brahmin ethos permeates it.

[When pointed out that Kamal Haasan and Mani Rathnam are significant
Brahmins in the industry today:] Kamal Hasan is a beef-eater who to
debrahminise even espoused the philosophy of the Dravidar Kazhagam.
Mani Rathnam is an intelligent filmmaker, he is a good entertainer,
and yet the intellectual class of the little magazines circle targets
every film he makes. There's an undercurrent of anti-brahminism in
everyday life.

The Tamil Brahmin community appears doomed. I see no possibility of a
good leadership emerging from this community. Jayendra Saraswati
certainly would not have made for a good leader. He is very poor in
his understanding of religion or politics. C. Rajagopalachari would
have been a good choice, but then he is not around. Institutions like
Thambras cannot really provide the leadership we need. A Brahmin
resurgence is very unlikely. Even in terms of Brahmin tradition, very
few are learning the Vedas.

Maths may offer freeships for Vedic pursuits but there are few
takers. Priesthood or the Vedic way of life is no longer a viable
means of livelihood. Nor are there any Brahmin landlords left. My
father-in-law owned a lot of land. Each time he got a daughter
married, he sold a part of it… today his family owns no land. Even
rituals have merely become social occasions. The marriage rituals are
also much-abbreviated to reduce costs. Fortunately, the upanayanam
(thread ceremony) still continues, but this is more an occasion to
meet up with relatives. Sandhyavandanam should be done three times a
day by a thread-wearing Brahmin. It is good thing to do. But who
performs it? A Brahmin does sandhyavandanam only once in his lifetime
and that is on the day the thread is bestowed on him. 50 years hence,
perhaps even upanayanam would be given up.

Rituals are not easy to follow. They require a lot of energy and
money. The 13-day post-death rituals are very, very difficult to
observe. When my sister died, we stopped with the cremation rituals.
Soon we may not have priests who know how to perform these obsequies.
I have told my sons not to perform them for me... I of course remember
my father on the day of his death, but I also wonder why are we really
bringing the spirits of the dead back to this stupid world.

[Guest]

The postion of Brahmanas in Tamil Nadu is basically like that of Whites in South Africa.

It is a question of do you stay and fight or do you flee for better opportunities.

Brahamana IQ is equal to that of the Northern Europeans, i.e. it is the highest in the world.

Brahmanas are also plagued by the same problems faced by the Nordics, namely, low birth rate, over-educated females, males moving toward atheism and becoming anti-Hindu.

Brahmanas like other high IQ people are also more individualistic and lack team work. Races with lower IQ have better group cohesion.

The problem is one of demoralization. The root cause is the Brahmana male becoming demoralized and losing faith in the Vedas. Once you loose faith in religion, you basically become a aimeless idiot.

Then females take advantage of the situation and become more assertive and loose. This results in Varna-sankara (mixed marriages) and leads to the destruction of the Aryan race as has been clearly indicated in the first chapter of Bhagavad Gita and also in the Manu Smrti.

So the solution is for Brahmana men to first shape themselves up mentally. Then everything will follow.

[Guest]

One more point.

I mentioned in the "History of Bengal" thread how the Bengali Brahmanas were foolish not to create a Kshatriya class to defend Aryan rule in Bengal.

The same thing applies in Tamil Nadu. The stupid Tamil Brahmana sat on his rear end not doing anything for centuries until the situation became desparate. They didn't even bother to take a census to find out what percentage they were of the population until the British came in!


Compare this with the Nepali Brahmanas who had the brain to create a large Kshatriya caste who form 16% of the population. Brahmanas form around 12%.

So this 28% dominant upper caste cannot be pushed around very easily.

By this logic , 50 years ago if a Shudra was born of 100-120+ IQ, such a talent would have been waste, because due to caste systems rigidity he couldn't have taken up a job that required intellect and he'd have died of utter poverty and hunger.
So, for the lower castes, someone with low IQ and amenable to menial tasks would have stood better chance of employment and hence longevity and reproductivity.
Over a generation such a situation will naturally result in a population of low IQ in the community (with exceptions of course).

Reservation or not, but prolonged and committed affirmative actions are required to pull up such population groups out of the sad situation.
