Go read Numerian's letter to his Senator
What Sec. Paulson wants you to believe is that catastrophe is approaching, but it can be averted if only Congress acts urgently to give him the extraordinary authority he is requesting. The implication is if you don't give him $700 billion in borrowing authority within a week, markets will collapse and it will be all your fault.
We've seen this drill before, with the Patriot Act and with the Iraq War authorization. The scare tactics, the urgency, the implied threat of blame for any failure - this is what the Bush administration does. Some of you in the Senate were able to stand up to this pressure, and that type of strength is desperately needed now.
If insolvency is here now for the big banks, the last thing you want to do is throw $700 billion of money that is not yours at bailing out the banks who created this disaster. You'll need every bit of that money to protect the taxpayers and their deposits in these banks when these financial companies are thrown into the bankruptcy courts. You'll need that money to make sure consumer deposits are protected with insurance, and you'll need it to keep the healthy parts of these banks that deal with consumers and businesses functioning until they come out of bankruptcy.
Numerian also has a financially literate explanation of Credit Default Swaps, to which I briefly, and illiterately, allude here.
