I look at the differnet social/government systems as a continuum that spans from capitalism to communism (leaving dictatorships out of this conversation).

Capitalism —> Socialism —-> Communism

As you move from capitalism to communism the amount of government intervention varies. In a true capitalist society it is all about the rights of the individual to be a free agent, to do whatever he or she feels will benifit themselves the most, survival of the fittest if you will.

On the other end of the spectrum is communism where every individual is expected to give everything they produce for the greater good of the whole.

Darwin’s natural selection is most like capitalism, through mutations and time organism try different things to one-up the other organisms, to arrive at the top of food chain. iPhones for example.

Capitalism I believe is our most natural state, requiring little interference from the state or the whole in fact no interference is best. Communism, and to a lesser extent socialism, takes us away from that more natural state and imposes rules and regulations to make us behave and care about one another. This forcing of everyone working for the good of the whole often requires a more aggressive and meddling government. Why, because people generally don’t want to cooperate. Look at the old USSR for instance, not true communism but full of rules and KGM etc.

A litle bit of every system can be found in any country, Sweden is far more socialist than we are, and that requires a bigger goverenment that gets more in your face if you don’t play nice.

Anyway wildly generalized, mainly because I thnk it take at least three beers to properly discuss.
