This highlights a severe weakness in capitalism as we practice it. Large fortunes are accumulated, then passed on to people who had almost nothing to do with accumulating the fortunes. The undeserving heirs then use the fortune to fund ways to undermine capitalism.
The only plausible solution that I can see, is for those who make the fortune try to insure that it goes to someone who worked for it. Not an easy task.
Excellent point and like you say, not an easy task.
The person building the fortune is probably, in most cases, too busy to pay much attention to his heirs as they’re growing to adulthood.
I believe that’s what has to happen to assure their wishes are carried out.
