American exceptionalism. What is it? How is it defined? Is it just another meaningless rhetorical phrase? I don't think so. In fact I think American exceptionalism is evident from all the things our society doesn't do. We are exceptional because we don't provide medical care as a basic human right, we are exceptional because a college education incurs massive personal debt, we are exceptional because we are the richest nation on earth with over forty million people living in poverty and the lowest economic mobility rate in the industrialized world......we are certainly exceptional.
No, we are exceptional because we created a country based on a philosophy that the government serves at the will of the people, not the other way around. We were also founded on the idea of individual liberty, and protecting the individual from the government.
Those problems you point out....come from abandoning our founding principals and reverting back to the belief that the government is better at running our lives than we are. The more you give the government to do, the more screwed up those things are, and you end up with the complaints that you have.
Healthcare, education, economic mobility....are all more under government control than ever before and they are more screwed up than ever before.....
