He doesn't have the money to do either of those things, though.

His estimated net worth is $150 billion. Wealth he spent his entire lifetime building. The majority of which is not even liquid assets.

The US government spent over $9 trillion. In 2020 alone.

If Gates had the means to end world hunger and poverty, the US could do it without Gates' help. 60 times over. Every year.

He's too rich for his own good not a doubt in my mind, that's bad enough in itself, no need to make shit up.
