Buffet, Gates, the Patagonia family, etc., all those Billionaires do is transfer all their wealth, tax free, into “charitable” entities that their descendants can continue to live off of, and profit from, indefinitely.
That by itself is sinister, but the worst part is that the majority of people actually believe they’re really giving away their wealth. So they cheat the system, that they already rigged, and it actually gives them a better public image.
