Is cheap people usually selfish?

A friend of mine ask me the following question: Is cheap people usually selfish? My instinct says no but I don't know what examples to give?

The 1st person got into my mind is Warren Buffet at his younger age. I like Warren Buffet and I think that he's the most honest and generous people in the whole universe. I read his biography. When he was young, I got a sense that he's cheap. He doesn't spend any money that's necessary because he knows that each penny he spent at younger age would worth 10, 20 and 30 times in the future.

The thing that bothers me a bit is he ask his son to pay rent for the farm. I am a person who focus on relationship. I don't quite understand that Warren Buffet asks the son to pay rent for the farm. I think this is the wrong thing to do.

My wife has a completely different opinion. She told me that Warren Buffet has an education fund for each child. He knows what's important for this child. She also told me that if the son doesn't pay rent for the farm, the son might not have the pressure to do an excellent job as a farmer if his Daddy pays rent for him. His son might stay in the same place for 10 years doing a lousy job as a farmer. I see my wife's point clearly and I agree with her somewhat. I know if my father pays everything for me, I will tend to be lay back, too.

I starts to understand what money is. Money is an object that measure our progress. When I am better, bigger, focus and driven, money will be attracted to me. When I am negative, guilty and lazy, money will get away from me. I can always tell by my own feeling that I am moving in a right direction and doing what I love to do and do it well. Money is simply just an important and objective instrument that tells me where I am.
