Andy Carnegie and Bill Gates
There is an interesting difference between the two. Gates is a recent convert to philanthropy. Carnegie, however, began at an early age. He decided that he would make a fortune and use it to contribute to a better world.
Carnegie came from a family of radical Chartists. Philanthropy was his way of being radical. So, he felt justified in screwing anybody — even sanctioning the bloody battle of Homestead to promote his philanthropy.
209: “… there are higher uses for surplus wealth than adding petty sums to the earnings of the masses. Trifling sums given to each every week or month — and the sums would be trifling indeed — would be frittered away, nine times out of 10, in things which pertain to the body and not to the spirit; upon richer food and drink, better clothing, more extravagant living, which are beneficial neither too rich or poor.”
