It is contradictory, complex, uncertain, unforeseen, and in perpetual moving. Nobody could control it perfectly. Trying to suddenly build a perfect society was the mistake the Marx, Lenin, and their disciples did. It is intellectual naivet to think that someone could conceive of a new society. In my opinion, the system in which we live is not important.
None is perfect.
Our duty is to try to make things tolerable and to improve it continuously. The key to progress is not in politics but in morality and economy. Politics is a necessary evil. The economy must be efficient, because the more efficient it is the easier people succeed in annihilating the stupidity of the politicians and lead their acts. The occidental countries have different political systems.
