The caste system dates back to the Vedic period (around ~1500 BC), it's engrained into the fabric of indian society and through the years this hasn't really diminished. For instance the British reinforced the notion of the Caste system, and so did Gandhi, for many it's not seen as something that should be stamped out, but a way of organising a social hierarchy. Modern Indian politics is controlled by the elite - all from high castes - so movement here is seen as politically difficult and unpopular. America's divisions are primarily race (and to an extent wealth), the British still have a strong sense of subconscious class, in that regard Indian society inherits fragments of both. Those of the SV Indian tech society who still propagate the system do it because they do not like seeing traditionally poor people from lower castes earning triple figure salaries in the US, and sometimes if you're extremely fortunate in India. Note: This is me playing the devils advocate, I'm absolutely not in favour of the caste system
