All of the extremely wealthy people I know are in favor of maaaive death taxes, of pretty much all wealth. However, none of these people inherited their money, and came from humble backgrounds, so my anecdata may not represent many of the wealthy.
Not to accuse them of being dishonest, but it also costs them nothing to say that, loudly and often, in a political environment where they know it's not going to happen.
These are private and personal discussions, ranging over many areas of politics where we disagree and agree. I have no reason to doubt them. Even with a massive tax eliminating inheritance, their children will lead charmed lives. They are more afraid of a dysfunctional family than their children suffering from material wants.
