The key to all this isn't some stupid "stimulus" effort by the government to throw money into the economy - that's been tried before and never really worked.
What really needs to happen is the US Gov't needs to suspend their mark-to-market accounting rules on banks. What this generally means is this. Currently, under mark to market rules, a bank must value all its assets per the CURRENT market, not a historical market value.
For example....Suppose you own a $600,000 house near a forest and have some other money assets. You go to borrow money from someone, full of knowledge that your house has a historical value of about $600,000.
A forest fire suddently looms up and approaches your house.
When you go to a bank for the loan, the bank sees the fire and doesn't accept your use of your house as collateral as they are "marking" your house to the current "market" as worth nothing....i.e. its going to burn down.
Historically its worth $600,000 but the bank, in its response to a potential fire on the house says its worth $0.
Suddenly the fire turns and your house is spared. But you couldn't get the loan as the bank only looked at the current, fluctuating value of the house and not its historical value.
In the banking industry, the government forces banks to have a level of reserve on hand and banks can only loan out so much money based on their "marked" assets. In this down market, those assets are VERY undervalued when compared to historical levels. So money is tightened since the banks are limited in what they can finance. The economy then further sinks, further reducing the assets the bank holds, further reducing available money, and the snowball down the hill occurs.
By suspending these mark to market rules, the money in the US would be freed up and certainly help the economy...much more than a ridiculous stimulus package that is really, truly a further attempt to strengthen government, not the economy.
