good Catholic boys like Bill Gates and Warren Buffet
I see that Gates married into Catholicism, but why do you say Buffett is Catholic? The "official story" is that he was raised Presbyterian but is now agnostic. "Freedom From Religion Foundation" lists him as a poster child.
Of course, the smart 'big boys' get around the inheritance tax with good lawyers and accountants.
The way this was done was to set up a "Charitable" foundation, put the kids on the board of directors, and rely on them to use the foundation to promote family and elite interests broadly construed. Gates and Buffett set up their foundation more or less along these lines, presumably not expecting such a change as Trump is now promulgating.
