I know you're trying to compare this to caste, but India is also literally still a casteist country.

America was explicitly a racial caste state until the Civil Rights Act passed in 1964.

India similarly outlawed caste discrimination in article 17 of it's constitution at its inception.

Of course laws cannot change centuries old social customs overnight. Which is why the US employs DEI to help equalize opportunity and India has gone as far as to implement quotas for the historically disenfranchised in the public sector.
