The world of pokemon is an idealist's utopia.
Save for mafia-esque organizations appearing every now and again, there is next to no crime. This is why it's considered normal and healthy for 10 year old children to leave their house to explore the world.
There is a lack of government needing to be present, save for a few likely under-worked police officers, and the international police force. This is because, in this utopian society, there isn't much that needs governing.
Healthcare for your pokemon is free. Why wouldn't it be for humans aswell? This explains why no one seems to be disabled, because everyone is able to be successfully treated.
