Many urban Indians have no idea how bad the caste situation is.

I'm a Northerner of a so-called upper caste (but not a Brahmin). I had to move to Chennai (a Southern city) for a year. I was shocked when apartment-hunting there. At every "to let" apartment visit, I would soon be asked if I were a Brahmin. Then the person would let me know they were a Brahmin, and that they would only rent to Brahmins. Nope, didn't get a decent apartment in that city. It seems all the nice property there is cornered by Brahmins.
