(our family’s foundation) and an affiliated DAF have made grants of more than $700m, have foundation assets of ~$1 billion still to give, and I am a signatory of the Giving Pledge. And unlike Melinda, every dollar of philanthropic gifts I have made, came from money I earned, not resources I married into.

All of that said, I don’t believe that philanthropy is the answer to societal problems.

has done more for the world with his for-profit enterprises than any philanthropist ever.

In my experience, many if not most philanthropic organizations are inefficient and/or ineffective. For-profit organizations are vastly more effective in addressing societal problems than non-profits.

Therefore, in my view, philanthropy should be focused on addressing societal issues for which there is no current for-profit solution.
