Speaking only about estate taxes, some of the discussion here is nuts. The Bezos story makes for good theater but it's not the rule for most rich people--say people between $50-$200 million in net worth that have sold their businesses (and paid income tax on the sale) and have a pool of investments and assets when they die. They are worried about asset preservation and/or income generation for their children, grandchildren, great grandchildren, and so on. I know two leading will and estate attorneys in Houston each with more than 30 years at this and they say that you can do everything right with things like revocable trusts and the marital by-pass trust, etc., but the 40% estate tax is real. They will also say that depending on how soon the next generation dies after the previous generation dies a $50 million estate can turn into an $18 million estate very quickly. Usually, the assets are invested very conservatively (again, it's all about asset preservation and income generation, not bitcoin-type investments) and the 40% estate tax can hit the heirs before the estate can grow back from the previous 40% hit. And when it's divided among numerous grandchildren and great grandchildren it's not like everyone is sitting on a beach earning 20%. For the vast majority of folks affected by it, the estate tax is a horribly unfair tax.
