King, nationalize as in the state owning the banks and doing whatever they want with them (lending money at special interest rates to their political cronies for example). This is not the case, the stake the government is taking in banks does not allow it to take part in the actual running of them; they cannot act as owners.
As far as "socialists" go I have to agree with you that the pressures exerted upon Fannie and Freddie by the Clinton administration back in 1999 lo have lax lending policies concerning minorities/ninjas (aka sub-prime) are really of the socialistic/demagogic kind and are the main cause for the present day financial situation.
