Hilarious that someone could avoid professional sports for the reason of wanting to "make real money," but I suppose when you end up a billionaire it was a good choice. From MSNBC:
"Now, in those days, you couldn't play baseball because there was no real...you know, it wasn't a thing. Plus my father was in the real estate business, which I didn't want to go into. I wanted to go into theater. I wanted to go into sports. But I also knew that was very limited because in those days you couldn't even make any money being a great baseball player."
Even today, funny enough, you can't make Trump money playing baseball.
