The problem lies in Democracy, it is not for nothing that it is called the least worst ruling system.
The difference between most democracies and dictatorships is that a dictatorship is despotism by minority and most democracies despotism by majority, not often are democracies systems of fairness.
No, it's not with democracy, it's with the values of the populace. If you have a predominately good people, then many political systems can work; if you have a predominately duped and corrupt people, no system can work.
If you think that the problem with the U.S. is that everyone is hopelessly enamored with Rorty or other postmodernists, then, I think maybe you are out of touch with "reality" just a little bit. :) I don't think the NRA is going to start quoting Derrida any time soon.
