Bill + Melinda Gates Foundation is a fun litmus test for leftists because you either have to claim (and secretly hope) Gates is a fraud or admit that not all billionaires are evil.

There’s no contradiction. Having that much money hoarded in the first place is a gross misallocation of social resources gained by not paying workers what their labor is worth, not to mention all the horrible acts Microsoft has committed to gain that profit. A leech who pays a few percent to charity is still antisocial and should be removed from society.
