So, the pokemon world is portrayed as this bright, happy little world where cute little monsters have fun and play games of skill with one another, for sport. You can capture them and befriend every single one, and love them like a family member. But I doubt many of you realize what is playing out in front you.

That should've raised a red flag, but it seems innocent enough, right? If you go out into the grass, a Rattata could get startled and scratch you! Or, it could sever an artery and its family could pick your skeleton clean.
Pokemon
are capable of killing.
"Sneasel scale trees by punching its hooked claws into bark. It seeks out unguarded nests and steals eggs for food while its parents are away."There are plenty of examples of pokemon having their 'prey' mentioned, but most should be common sense.
So, Wild Pokemon think you're prey, but once they're placed into a magical ball, they're instantly loyal to you, unless you're just a complete fuck-up.
I'm sure being brainwashed is unpleasant, which is why you have to weaken them first, so their flailing in terror and anger doesn't break the ball. Presumably you can only brainwash conscious pokemon, which would explain why completely knocking them out doesn't work. Look at the Luxury/Friend Ball. If they were so amazing, surely a pokemon wouldn't want to break out. But they still struggle just as much a regular pokeball, and are instantly happy when you capture them.
So, the point these games seem to make is that you need physical power to be rich and powerful. In this world, you battle for money. It sounds like betting on a sporting event, right? Well, not exactly. Betting implies you have a choice in the matter.
If you see another trainer, he may challenge you to a battle. The stakes? You lose, you lose half of all the money you own. You also black out and end up in a pokemon center somehow. Oh, and one more thing:
