Why has the stock market fallen so much as politicians have talked about nationalizing the banks? If this was such a wonderful way of fixing credit markets, wouldn’t you think that stocks would go up?

No.

Not until the government organizes and
gets out.

Where have you found that Obama has said he plans
to run the banks, and keep the banks in government control?
Where? I have not found it yet...

stop it with the silly stuff.
You can call it Nationalizing or whatever. But the degree
to which the govt. takes control, manages, and for how long
are the real issues.

Just say we should let the banks fail and watch the market.
It will dive. But imo it will come back. Is there a middle ground?
