He became a billionaire. He gave away his wealth over the course of his lifetime. He meets the criteria of a billionaire and a person who has done something good. Other billionaires are having trouble due to the scale of giving away so much money and vetting who receives it. McKenzie Bezos became a billionaire when she split with Jeff Bezos. She then came under fire not for giving away money, but for not vetting who it was being given to. People who think giving away money is easy or doesn't require some hard work don't understand the scale they're talking about I think.

Like. Imagine Elon Musk trying to give away $144Billion. To a non-corrupt individual, entity, or charity. We can't even eliminate corruption completely in regular charities that only handle millions of dollars yearly. That's the equivalent of some countries'whole GDP. But we can't eliminate corruption in just about any country in the world.

If the goal is to do something good, it requires work. That's an important part to remember.
