The source of the problem was overerly agressive borrowing by unqalified home buyers - Wall Street was not involved; blame the naive buyers and the overly optomistic banks/mortgage companies. Second level blame goes to the financial institutions (mainly Fannie Mae and Freddie Mac) who then purchased those mortgages, bundled them into complex financial packages and peddled them to major investment houses who later sold them to Pension Plans, Mutual Funds, and Insurance Companies - and it is these folks who are holding most of the bag today.

Wall Street is inextricably linked to everything inasmuch as it's the stock failures of those institutions that the "bailout" will help salvage. The daily trading here and around the world is as much the heart of the "financial community" as any individual company. When Wall Street crashes, the economy goes with it. And ask yourself why these institutions are in trouble now? They were riding a wave of inflated stocks that were soaring with mortgage loans, etc., etc., that, when markers began to be called in, the consumers -- the uneducated masses living head and shoulders above their income means -- could not pay. Panic ensued and here we are. Yes, "institutions" failed due to poor management. But do not for one minute think Wall Street is an innocent bystander. This bailout will most definitely have an impact on trading and the Dow Jones.
Whoever it was who first decided to sell the idea that the housing market was vastly undervalued and then saw it become horrifically overvalued is, ultimately, the one to blame. There are basic levels of blame and there are complex levels of blame. Brokers, mortgage companies/lenders, consumers and stock traders are ALL IN IT together.
And of course, those of us who sit by and watch are the ones who will pay.
