Not sure that you're right about the "minority" aspect but, when "kids" come into the business, they aren't usually as driven as the person who started the business with blood, sweat and tears and of course, generally, are lacking in experience.
Work ethic is probably the most important attribute plus, some nouse on what makes things tick.

Younger managers often make "rookie" mistakes but, can more than make up for that with new ideas.
However, luck is definitely important as well.

Erm, did you even read your own link?

• An entire topicMy 6 years of secondary education cost more than your average 2 up 2 down house in Northern Britain and I can claim to have received more "steps up" than most, but I was educated in a country that believed in ALL TRUTHS being told, not just the convenient ones. It would seem spoon feeding the lower classes stories of Otto Von Bismark with his pointy hat or the really short 5"11" Napoleon (both who you defeated) are more important that the stuff that mattered.....like why Israel is so hated by the Arabs (british thing), why India and Pakistan are at war (British Thing), why Hong Kong residents are rioting (British Thing), why Hitler rose to prominence so quickly after WWI (british thing)....oh, and who transported most of those african slaves that caused the US civil war.....yep, A british thing too. None of this is taught to your kids......why do you think that is?'"
