Do you have any numbers on that? It seems a lot more common for very wealthy families to tie up their money in trusts that their children can't access, both to avoid taxes and to ensure there will always be a giant pile of money generating low amounts of interest. Plus, don't the kids lose an incentive to innovate? Where does that cost factor in? If you already have one private jet, the marginal benefit of another isn't that big. not sure why somebody downvoted this. All of the very wealthy people I've met who got that way through inheritance don't have piles of gold in a vault. They have a guaranteed income, and access to all kinds of assets like houses, vehicles, memberships, etc. They don't have millions to invest.
