Not directing this part at Rob: I have met plenty of people over the years that bemoan the lack of opportunity in the US, that tell me how it is impossible to break out of your class, that see greener grass in other pastures. For every one of those people I've also met someone who had an idea and ran with it. They left the whining about the playing field not being perfectly level behind and actually stood up and DID something about it. Some failed, some succeeded, some became fantastically rich. Most of the ones who failed, including me (several times), went on to try again because that is their nature. Almost all of the ones who succeeded were the ones who failed at the first few attempts.
It's not the political climate that truly limits us. There are amazing success stories that came out of Stalin's Russia and Aristide's Haiti and any number of other places so oppressive that you wonder how it would even be possible. Hardly comparable to the US. Fear imposes limits, but not fear of what a government will do. Government actions only require strategy to work with. Limits are contained in that 6" space between your ears, but to admit that means dealing with the prickly issue of personal responsibility. Falling short of our goals might be more our fault than the government's. Ouch.
Ok Rob since you are carring the torch in this conversation, let me ask you this... If you had no financial limitations and could afford both the best health insurance available and the best health care for things not covered by insurance would you still be looking at Uruguay/Argentina/Chile? And #2, have you actually ever been down there?
