No its not. While the Indian caste system is mostly dead (at least in the educated upper class circles I travel, mostly full of brahmins), it does play a social role.

Us capitalism is nothing like it. Something closer to the caste system might be the tribalist cultural grouping of people in the us (e.g. fishtown and Charles Murrays other subgroups, or Scott Alexanders reds and blues).

I know its fun to say capitalism is just like all historical bad things, but its silly.
