Donations To Already Wealthy Colleges

Y’all are doing awesome by contributing as much as you can to your colleges and I admire the motives but I’m talking about mega donors. People like Bill Gates and Warren Buffet etc can also focus their philanthropy on their families, colleges and towns but they choose to look beyond their personal sphere. For example, similar amount of money can raise a lot more people through Khan Academy than through Harvard, it can do more at Doctors Without Borders or UNICEF than Mount Sinai Health System.
