I have a theory that goes like this:
order exists within chaos
Thus, in order to create a sustainable system, chaos must be considered.
What does this mean for countries;
that the systems governing them will ultimately fail regardless of its form. This is because all governments are trying to maintain a country and enforce order with only one set of laws.
For instance, some law is passed that kills innovation and paralyzes the creative, only because a few morons can't deal with some issues in life. This is not the way to run a country, that is, if the idea is to maintain the country properly.
Most humans are stupid, but that doesn't mean everyone's life should be controlled by the state because of the stupidity of the majority. The majority by their own will, will live in communist regions, where the state gives them a job and in return controls every aspect of their lives. (Why will they be willing to live in communist regions?) Because they won't be able to survive in true capitalist regions, where there are no government handouts and no food stamps, yet very little taxes and hardly any bureaucracy.
