1. The US economy is in a state of almost irreparable recession. The housing market has crashed in the southern states, has moved to California and soon could advance on the richer, northern metropolises. Combine that with over loaned mortgages to people who couldn't afford a 40-year lease and banks dropping out like flies and you lose a financial base on which to rebuild the economy.
Then you have to look at the job situation. A great deal of America's manufacturing and management positions are not held by Americans. Instead, workers and managers in India, China, Thailand, etc. are producing all of the necessities that the country uses. Now, it's all fine and good to have your goods produced for a criminally low price, but there needs to be money in the consumer's hands if you are even going to consider purchasing the item. So, the fact that the stores are full of electronics and food doesn't matter if the people have no jobs to pay for them.
