Or you start giving earlier (depending how presents are taxed), and your nieces and nephews receive the support when they are young and strapped for cash. I think this would help stimulating the economy much more than if your heirs are in their 50s+, when they (on average) don't need any money and just keep hording it.
I’m not hoarding anything. They’re getting checks regularly. They’d be getting a lot more if I weren’t taxed at obscene rates relative to billionaires.
