Let me shake your realities. Caste system is here to stay. As long as you have an ability to perceive and process reality you will continue to judge people and that will give rise to a partition mentality. Someone aptly said that "back in the days we used to have caste system, today we have class system." No matter what you call it, the system to divide the people will find its existence in our society. So all you people who say that you are above this system are mere liars and opportunists. When the opportunity strikes you will show your real color. Think about it.
