I see what you're trying to say. But most of the world is not doing better than the U.S in terms of regulating capitalism. Sadly. Guessing you live somewhere in Europe. That's good for you.

Take a look at Latin America, Africa, Southeast Asia, West Asia, China, Middle East, Eastern Europe (most of the world by population). And you will find rampantly unregulated, capitalist influenced politics across the board. You will find actual slavery. Human rights abuse. Corruption. Ecological destruction. Massive socioeconomic stratification. All on a level much more intense than what can be found in the U.S.

Places like India, Philippines, China, Brazil, Mexico, Russia, just to name a few big ones that come to mind. People immigrate from these places to the U.S and it aint for the good weather.

This coming from a Canadian, which, while we try to run a mixed system here also, people still get exploited a bit on the lower end of the pay scale.
