The poster has obviously made a few poor life choices but his assumption that he would have more if musk had less. I don't think so.
Another thing is that there is always going to be someone who has more than you and if you spend your time thinking about it, you will soon be trying to find a way to get "Your Fair Share" of someone else's wealth. It's called "coveting" and it's covered in the BIG 10 rules of life.
And finally it might be because of bad health, his or maybe someone in his family. Or maybe he didn't have a family he could count on for support of some kind.

Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
