There are so many people that say that they would be benevolent if they had money. Do you know a case of this being true?

A lot of people, including myself, think about the wonderfull things that they would do if they have enough money . I do belive that this would happen but i also belive that money makes your perspective change. The small amount of people that got monetary success, are not really that given, even if they come from a humble beginning (relatively to their position now). So i wonder, am i extremely innocent thinking that i would be different or do you know cases that people are really giving a lot, now that they have the opportunity to do so? Keep in mind that I'm not talking about, as much, charity work or giving to an association, but more like giving a bit to some of people that are closer (family, friends, etc...)
