That's assuming our world magically attained Pokemon in it's current state. If they were real and had always existed, the world as we know it and even the one in the anime would be structured completely different. It wouldn't be socialized with Pokemon Centers... no one works like they do in this world and therefore social taxes wouldn't be applied magically like they are in the anime. It would be anarchy, little structure... with beings that could obliterate cites, even continents in the hands of anyone who wishes. Pokemon would rule the world, not people.
