Yep. And caste based discrimination is legal in the USA. Its not a protected EEOC class, as much as that doesn't matter in our legal environment.

So yeah, you can discriminate against Dalits, and hire predominantly Brahmins.

Except in Seattle, which explicitly bans caste discrimination as of 2023, and in California, which interprets its own state anti-discrimination laws to already include caste discrimination in other broader categories (which was the reason Governor Newsom gave when he vetoed a bill in 2023 to explicitly ban caste discrimination).

Quite a lot of tech companies hire in either Seattle, California, or both.
