Yes... yet the world was also communicating AND traveling rapidly. Correlation does not equal causation.

Whether you are capitalist or communist none of these places were isolationists. They still traded, they still operated humanitarian goals, etc. They ALL are going up. The rapid rise to me looks to be more likely due to global equalization and sharing of health related technologies, inventions, and food.

I still say there is no evidence that capitalism or communism were the source of these things. I think it is far more likely due to be related to long distance communication and mass transit.
