I am reading the question as what historical accidents made it socially acceptable. Here is a factor that I think might play a role: there is a lot more power in the sub-continent at lower levels of government. Specifically, the SP/DCP system allows the local policeman to act as a unilateral mini-judge, often settling disputes to his (rarely are they female) liking. http://en.wikipedia.org/wiki/Superintendent_(police) http://en.wikipedia.org/wiki/Superintendent_(police) This inordinate power gives them a lot more scope for corruption. This system was set up specifically because the British needed to control a vast country with a few people that had to be posted to various regions. I also agree with the other people who point out that poverty plays a role.
