Oh, Please. Don't put the US on a pedestal. There is a shitload of issues that the US needs to fix and a little humility in accepting that others have better solutions, is one of them.
For all of the US's problems, Pax Americana has been statistically pretty damn successful.
The internal issues of the US are of no concern to other nations, the only thing they care about is what the US can do for them and the rest of the world.
