This is a nice gesture but a fat stack of paper only goes so far even if it is 600 billion dollars.
Imagine the kind of change these business greats would make if they pooled their knowledge and talents to create a chain of self sufficient schools, for example (this has
already been done at least once that I know of). For something like this the return is
infinite.
I don't know, not trying to belittle the gesture at all. But IMO what nonprofit charities need isn't more money, it's innovation, framework for solid self sufficiency, and business accumen.
