Is the U.S. heading for a meltdown? Perhaps.
Is it going to happen soon? No
Will the U.S. (and its allies) allow this to happen? Of course not.

The complexities of the United States economy is as complex as any economy around the world. All economies have its high and low times. And right now, the US is experiencing a bump. A slowdown in economy is more precise than saying that the US is at its phase towards folding up. Remember, the World Bank is always headed by an American, IMF is always Western European, and ADB is always Japanese. As far as I know, if ever it comes to that stage, the entire world we be severely affected in a big way. Just my 2 cents.
