The only 'charity' billionaires ever give is money they would've had to lose anyway, and almost always exclusively to themselves. Said donation either funds political causes to directly benefit themselves, goes to an organisation who can then do whatever at the billionaire's whim, directly advocates for their other business profits, pays them or their family/friends excessive amounts, and is all donated so as to pay no more than they would've in tax anyway.
