Cygnus - Point taken. I think that we are pretty much on the same page.

Eurosocialist AND TFBM -
It would seem that in theory Democractic capitalism is inward-looking and not in the planet's best interest, in the same way that, in theory, Communism sounded great on paper about 80 years ago. It is deregulation and the increased economic activity of capitalism that actually ties nations together with international trade and multinational corporations. This leads to the development of effective international law. That is the most effective contribution that can be made to global governance at this point.

True socializing of costs for international projects is near impossible(witness Kyoto), in a practical sense, so socialism is not even close to workable as a means of global government.
