I agree with the others. Debt is a problem. However the US Market is the world's biggest customer. As long as we have a currency system Japan and China and others will continue to by back US debt.
Japan is too small a country and has no choice. China is to large a country and has no choice. Both have precious few resources. Both need the US customer base. Look at what they put out. Japan the best cars. China the cheapest shit in the world.
The US market will rebound. The rich and or wise make money no matter what market does. A crash like back in 1932 is unlikely. The key is debt management. If you learn to manage your debt you will survive. If not you will crash and burn.
The housing bubble allowed alot to people to get rich. Unrealistic people should have understood that a $300,000 home cannot be had for $500.00 a month.
