I still think the media plays a part in the economy. After the Dems took control of congress, the economy took a slight down turn, but it really accelerated during the presidential primaries when the Dems were pushing the idea that the economy was bad and it was President Bush' fault. The media went along and really hyped all the negatives of the economy. That seemed to make it get much worse.
Here is how consumer spending works. If you have money in your pocket, you spend it. If you have a credit line you spend it.
If you don't have neither you don't spend money.
The economy went to hell because the Beranank reacted too slowly to the rising commodity prices with his interest policies and by the time he did react, it was too late and he blew up the housing market at the same time.
For his incompetence, he got a second term. Because everyone knows low interest rates are great for capital formation and real investment that creates jobs.
