When you say this does not make it okay, it seems you simply have no clue the level of disparity most people in India are dealing with. Unless someone magically make every one earn >10K dollars per annum, 5K is lot of money in country where median income is about 600 dollars yearly.

No, it doesn't make the practice ok, but it's important to identify the right problem if you want to solve it.
