The First World World

If all countries were like America, with massive use of technology, industrialization, health care, government, transportation, education, and all other aspects of a first world country, what would happen?  What would go wrong?  How long could such a world sustain itself before resulting in chaos, overpopulation, war, famine, pestilence, and all kinds of destruction of the environment?

True democracy will never exist, capitalists will always beat those politically correct pansies down.
Look at how horrible America is now.
Compare this to the 70's and 80's when we scoffed at PC. Democracy is even more destructive than socialism.
