The United States is on the wrong side of that sine wave, on the downslope. From Jeff Thomas at internationalman.com:

Almost daily, someone (often a European or North American) comments to me that the world is falling apart. The government is becoming dictatorial, the people are becoming more socialistic and political correctness is no longer an option, it’s a mandate and you’d better get on board.
This trend is not by any means imagined, but it would be incorrect to say that “the world is falling apart.” If we spend time travelling the world, what we see is that parts of it (primarily the former “free world”) is unquestionably in a state of political, economic, social and moral decline.
The good news is that many other parts of the world are impacted less; others are hardly affected at all and, in still other cases, countries are thriving.
What’s often missed, due to myopia, is that, in any era, there are always some countries that are burning out at the same time as others are on the rise.
Cultures and nations pass through cycles, much like the sine waves above. Any nation that undergoes a social, political and economic collapse ends up hitting the skids and staying there for a while. Often, the spoiled, complacent generation is unable to affect a recovery. However, the next generation learns to recognize that the only way that they can move ahead is to get out and work. Be ambitious, be self-reliant, act responsibly and, eventually, you’ll improve your life.
