The progressives are right that there is no way Gates can spend $50 billion on himself. He can only eat three meals a day and wear one set of clothes at a time. Even his heirs can be provided for with a fraction of that amount. Gates actually knows this. He has vowed to give away most of his fortune to charity. Nor is he waiting for death to do this. He has already given away billions. He buys mosquito nets for people in poor countries so that they don't get malaria. He invests in medical research. He funds educational projects in America and abroad.
