Should we blame corporate America our ourselves for the economy?

The net US savings rate has dropped from about 10% to less than zero since 1980 and and people thought the did not need to save because they could get rich in the market or in real estate, and that is at the root of many of our problems. Many people erred and purchased homes that were over priced and banks gave them mortgages for the inflated prices, and even used creative financing deals to encourage people to buy, and both thought it was safe because the price of the house was "sure" to increase.. The majority of us also voted for politicians that promised us lower taxes that would pay for themselves, and did not pay attention the the government deficit that was a large part of the low net savings. Greedy wall Street bankers played fast and lose with other peoples money and took the nations problems and turned into a banking crisis. There is more than enough blame to go around, but the lesson should be that unrestrained capitalism is not stable, and that financial firm suffer form moral hazarded the must be restrained, and that the government will not do the job if voters are not not responsible in their own life and do not demand that the government be also. The most frighten thing is that even with the almost half trillion dollar deficit that does not even include the cost of the bail outs and the war, people are asking which candidate will cut their taxes the most.
