If you ever get wealthy and your interest is in keeping the next generation wealthy, you set up a trust with stricts rules on keeping up with inflation, balancing accounts to even out the distribution and an absolute iron gate against drawing out the principal.

The long-long-long term generation wealth families don’t just hand the next generation an enormous pile of cash. They hand them the right to continually receive cash from a trust.

Wasn't there a family that would only have one heir to the money, incentivizing having only one or 2 children and both raised\groomed to not fuck up the money. Like if backup kid needed money, they'd get a loan from the trust but have to pay it back with interest. They have a family estate so if anyone fucks up they don't end up homeless. With so many advisers making sure the money is OK above all else.

I swear the Medici family still has an heir living off of that generational wealth

That’s why you create a family foundation that controls it so that no one person can ruin things. The family as a whole has to decide what to do when there’s any major decision.
