Quote from lolatency:
Because unemployment will only get worse. GM just sent out pink slips to white collar employees. GM goes, supply chain goes, and we're looking at 3mil+ more jobs gone. There's a consumer spending contraction in place.
Second, if China does start to move to kill the dollar, the cost of consumer goods will go up. They can't maintain that loose-peg. If consumer buying power goes down, we get hit with a double whammy over top of the unemployment. Clearly, China is not pleased with the way the US is managing things. They're going to try and save their investment.
If unemployment continues to rise then yes, getting people to spend will absolutely be a problem.
I believe what you're talking about is stagflation. This would be a problem. But I think people are putting the odds of China doing something drastic way too high. China knows their economy will be devastated in this scenario.
