I understand that in the pokemon games, you get paid by other trainers when you beat them. If the world of pokemon were real, would that system still apply?

Yes, definitely.. since that's how becoming a trainer would be even remotely plausible.

I think that would be like gambling... So I'd say they wouldn't let minors, which is odd, because in the games you are like 10...

If the system didn't apply how the hell will the Elite 4 and everyone earn ? 0_o

I am saying about Kids and all.

There can be different ways to implement salary's how do sports guys get their moneys..?

As I understand it, once one becomes a trainer he/she assumes all the rights and responsibilities of an adult, so of course they would let this happen. They also have slot machines in the games, and no one ever stops the said 10 year old from using one.

Pokémon battles are barely comparable to gambling, it depends on skill, not (entirely) on luck.

Anyway. But i don't think kids are supposed to play with money.

Kids now-a-days do what they aren't supposed to do....

I know. But not all of em.

Hey in Johto your mom doesnt exactly trust you!!
Your money gets magically transported to her instead!!

Hey yes

If you think you can travel a region ALONE, you are pretty much adult...>_<

People would shoot you if they lose.
