Actually, I only have an anecdotal evidence: from my personal experience.
I know a person who described her friendship with a person from a lower caste and how hard it was for the person from the smaller caste to get a better job precisely because everyone though that she is supposed to do only lower-tier jobs, as people of her caste "should".
The discrimination is still very much present: it's really hard to overcome a very old prejudice in people: people still perceive people of lower casts as "less worthy".
If this was not the caste, the regular support from the government for the lower castes (for example reserved seats at the universities) would be discontinued. (this is an example you can use: the government still thinks it's necessary to help the lower castes, if there was no more discrimination, they would have stopped). <span />
