Earlier quoted context omitted.
I don't want to 'take it back.' But, I feel donations should not be tax deductible. Why should I subsidize anything someone feels is worth donating for?
I edited my comment. By take back I did not mean the current wealth from of the current generation of wealthy. But take-back over generations using very large marginal tax rates. E.g. 'solve' the problem of the 0.1% being so rich.
IMO, the balance point is setting things up so the default is wealth is not maintained across several generations (3+), even though it can be passed down 1 or 2 generations and can be maintained with care past that point.
PS: I say this with many wealthy friends and family. It's surprisingly destructive and I don't want to setup multi generational wealth for my great grand children.
