>Passing off wealth and prestige by lineage has long been shown to be a bad idea. The next generation typically just screws it up.
In Japan there's an old saying that the success of a family is determined with the third generation.
The first builds the family empire. The second grows up seeing the first build it up and thus knows how to maintain it. The third grows up already having the empire and doesn't know how to maintain it, whether he can pass it on is essentially a dice roll. The fourth generation onwards, if the third succeeded, can refer to the family records and keep things going mostly indefinitely or realizes it's time to hand it off to different blood at that point.
