Why can't normal households and businesses get bailout from the Treasury/Fed?

If the financial crisis makes difficult to extend credits to household and businesses, you should bail out those poor households and businesses that cannot get such credit, NOT the devils in Wall Street. I just don't understand why such allegation can justify bailing the devils in Wall Street!

Presumably, normal households and businesses can borrow from the US government when the Treasury and the Fed are so eager to use at least USD700 billions to help the economy and the reason is given that these poor households and businesses can't get credits. I just can't understand and still can't see why we should bail out Wall Street.

If we looking for stability, is it the best stability when ordinary households and businesses can borrow money to continue their normal lives? What is more unstable than paying at least USD700 billions to toxic debts and dirts at full maturity value? All investors holding the US dollar and assets should cry aloud to protest against such action and the financial system in US will become truly unstable!

Yes, help the devils in Wall Street and give up everything else.
