I'm not sure how that's any different than football (soccer) or football (American) or anything else. You need talent as a kid. You need money to fund travel

I'm not sure how that's any different than football (soccer) or football (American) or anything else. You need talent as a kid. You need money to fund travel and equipment (either from mom & dad, or the local academy/development squad, or donors). You need to find a coach who can get the most out of your genetics AND find a path for you to go pro. And on and on.
