The claims made in this post are in dire need of citations, and don't strike me as believable. And just FWIW, most first-generation Indians in America couldn't give two shits about the caste system.
Only older heads who immigrated here are the lions share of individuals perpetuating this caste based discrimination. Please state your sources if you disagree with my assessment of first generation born Americans of South Asian descent working in big tech and Silicon Valley.
Your comment supports my observations. The newly-arrived Indians really don't like reservation and therefore care about caste. Second generation non-Brahmins in the US don't care about caste because it doesn't affect them.
