Wouldn't hurt him to donate a couple hundred billion.... Maybe start a science foundation or something. Jesus fuck I'm not a socialist and I don't hate him or feel resentment, I quite like him, but he needs to do some serious charity.
The hood done by space x is far better than any charity,
Advancing space exploration requires tech that solves myriads of problems here on earth, battery tech, non-fossil energy, ag tech, carbon capture, and more
Also he doesn't have 300 billion dollars Forbes estimates his wealth at 300 billion, this ranges from any property and cash he has to stocks, bonds and other investments to the very nebulous things like the value of a privately held company
