The money isn’t going to be based on athletic performance for most females. So the hot pole vaulter gets a lot of money and the champion shot putter gets basically nothing.
So? That’s just as true for men. You think Tom Brady would be getting all those side gigs if he didn’t look like a GQ model? Plenty of guys who (at least then) were more successful as QB than him but not as good looking didn’t get as many side gigs. If Peyton Manning wasn’t funny he sure wouldn’t be getting them, and nobody asks him to model anything.
