I have seriously mixed feelings about this kind of philanthropy. Yes, it is good that he's going to give his wealth away like this. I do not want to diminish his efforts in that!

But also, why collect such wealth in the first place? What was the point? Was the money really better off being hoarded by one person with the fingers crossed hope that they'll spend it altruistically someday? The existence of the wealth imbalance itself, and the general practice of wealth hoarding, are frustrating counterbalances to the good of giving it away.
