@Lando,
China is not "lending" money to the US, they're buying US debt, there is a big difference.
There is no "saving" the economy, it was designed to fail. An economy CANNOT be maintained when EVERY penny in the economy is DEBT owed to a private, for profit banking cartel. Our Republic has been fighting against what is effectively the Bank of England since it broke away in 1776.
Every "improvement" that we see in our economy is the result of the Fed printing money. It is analogous to giving a addict going through withdrawal another fix and saying, "gee look, they seem to be improving." It's been 100 years, and the US Dollar has lost nearly 99% of its true buying power. It doesn't appear that way to us as there is so much more crap to buy than there was 100 years ago, even 10 years ago. But, make no mistake about it, it will soon be 100%, and then the Federal Reserve will, by design, OWN EVERYTHING.
