I guess the factor of growing up with wealth often means that one grows up with the right education as well.
Yes, this is often the case. But I wonder, without the "necessity", is the drive there? I know many people who's parents built successful businesses and in the end, their children weren't interested in any of it at all - though they wanted to inherit the wealth from it. As you said, they didn't have the hunger, as they were always full.
China, the most capitalist communist country ever :)
