We were exceptional once; we're not currently. We could be again but attitudes will have to change. We were exceptional when we wanted to be here, when we thought being American was the best thing in the world. The past 50 years the inflow of new citizens didn't want to come here to be American. They wanted to come her to make a bankroll and return home. Now people come here to make the country worse than the one they came from, so that they can return once their former country is better in comparison.
imho the problem is, we have become splintered groups of citizens that only care about their own self interests.
