What Could Go Wrong?

If you took a typical neighborhood, with 10 houses and ten families, made six households work, at gunpoint, to pay for everything in the other 4 households, what could go wrong? I think the answer is obvious. Expand this scenario to the size of the United States, and you can see the problem. It's that simple and anyone that can't see this problem is probably living in one of the households getting all the free stuff.
