Making it illegal does not make it go away. Like racisim has not ended. They need to bring in reservations in education and govt jobs, a strong act like the sc/st act to ensure marginalized people get their due.
No that would be idiotic because most of the time the discrimination has nothing to do with Caste.
Different areas of india have completely different cultures (languages, foods, customs, etc.)
Most of the discrimination is based on where you're from (do you speak tamil vs. hindi vs gujarati...)
People want to hire people who are similar to them. Chasing caste is the wrong issue.
India has thousands of years of cultural history & practices. America has...250 years?
Applying your mental models from American politics to India (which is far more complicated) and then forming a strong opinion (without knowing anything about indian culture) is hilariously idiotic.
There's far more things indian discriminate on other than caste. Location, language, family group, language-spoken, wealth, etc. And obviously political views.
Half the time you have no idea what caste someone is.
