The title of this thread would be of the same relevance 300 years ago as it would 300 years from now. The U.S has always dealt with problems of some sort. If you don't like a here then you should go. I am not saying this in a mean manner either. You alone can not do anything to change the problems you mention, so why complain about them.
I would personally go somewhere like Australia, nice and sunny. Europe is nice too. Sweden, Norway, Finland, Switzerland etc. I know if I did not like it here I would pack my bags and leave. Why worry about the problems of the U.S if they do not worry about your problems. Unless you are some type of humanitarian, you should do what makes you happy because the U.S or the World will not stop to hear your complaints, and it will just continue to revolve, evolve, and make its course with or without you.
