They work in healthcare, education, gender equality initiatives, green energy..

I’m not a fan of MSFT but there are worse uses of the money he made from the company.

I think it’s a bit unfair to categorize all of his contributions to charity as “not charitable”.

His "charitable" contributions are only in place to charity wash his awful actions in the past and now. And it worked, everyone thinks of Saint Bill and his supposed good deeds while forgetting what he actually did or doing right now.

I don't think a healthy society has anything close to our level of wealth concentration, but even if he's made mistakes, he's saved many millions of lives.

Compare that to Elon Musk, who uses his Musk Foundation as a tax shelter, only spending from it for a private school for his children.

And how many people would have been saved if he didn't forcibly extracted that money from society to begin with?

Because it's almost impossible to not help someone if he just throw wads of money at random. What important is how many people weren't saved because he decided to be a middle man in all of it?

Way, way fewer. Any billionaire you've heard of is almost certainly a net creator of a huge amount of value, by successfully leading a company in a capitalist system that made enough money selling products or services to make its shareholders worth billions of dollars. This isn't forcibly extracting money from society, this is exactly what net-value-creation looks like in the world.
