First, this was suggested and discussed a week or two ago but some things never die.
The idea was about getting rid of perpetual family privilege and the continued accumulation of wealth into fewer and fewer hands. The model is what Bill Gates, Warren Buffett and many super-rich already follow. As
Buffett famously put it, the perfect amount to leave children is
“enough money so that they would feel they could do anything, but not so much that they could do nothing.” In Gates case that is $10 million. Wealth is power and because you may have been successful and become powerful I don't believe that means that all of your heirs for the foreseeable generations should also hold that power.
I think Buffett's quote above is perfect.
