This is not a difference in countries but in the age of money in the family line and what parents tell kids they should value. There's a natural transition from doing well at business in one generation to then shift the family focus to policy be it in politics, philanthropy, or technical (mostly law and finance) roles of prestige in the bureaucracy (ie SEC, district attorney office) which are roles that you can swing for if you don't care about money. If the kids revolt against this they'll do the same low reward / high prestige move except they'll try to impress their friends instead of their family, and go into art.
