I am beginning to think China is a country with more democracy then the US. I can't wait when China is the most powerful country in the world, and knock US off the rank. 
You may get your wish, but the recent experience of countries like the Philippines gives a preview of how much fun it is to deal with an ascendant China.
There is no doubt that US power is eroding and the NSA spying is horrible but there is still a lot of idealism in the US and its problems are on the front page for everyone to see. Many other countries try and hide and cover up their problems often attempting to deflect blame somehow to the US.
