If I had a million dollars for every ultra rich dude in my lifetime who said he's going to give away all his money, I'd also be a billionare.

Bezos is a monopolist, tax cheat, predatory capitalist. I'll bet you €1000 that his version of "giving away all his money" will result in:

1) The entity that he gives all his money to not owing any taxes; and

2) That entity being controlled by him.

The Bill and Melinda Gates Foundation ring a bell? It should. Same story from Bill. Same scam for tax payers.
