Transparency. Release the presentation Paulson gave to congressional leaders that supposedly has them all spooked. Give us the data and information, and let outside economists pore over the numbers and reach independent conclusions. The Bushies lie and have zero credibility. We can't trust anything they say.
Timing. Why the sudden rush, when the administration has been working on this plan for months? Seems more than a little suspicious.
Solution. We don't know what the problem is, so we really don't know if this solution addresses that problem. What we do know is that it's targeted not just at failing institutions, but any old financial firm on Wall Street that wants a piece of our money. Even those that "are very successful banks and investment houses that have done very well". Heck, did I say "on Wall Street"? I almost forgot. Any foreign bank can apply!
Details. Why $700 billion? Why not start off with, say, $75 billion. Is the emergency so dire that Treasury will spend all $700 billion next week? Doubtful. So put in what would amount to a bridge loan until people have had a chance to full understand the magnitude and severity of the problem. If it's truly as bad as people say it is, further moneys can be appropriated.
