Looks like these so called OBCs, SCs and STs will soon want reservations in U.S. Universities as well. I was once asked by a person who was from an SC background whether U.S. Universities will allow him to be taken as he was from backward class.
The true reason for the caste system not disappearing in India is not because of the Forward caste people not accepting these so called backward caste people into the mainstream. It is because these backward class people themselves like to keep calling themselves as SCs, STs etc...
How else will they reap the benefits of the reservations once they become forward castes...?
