One way to deal with TBTF banks

Richard Fisher proposes that the Too-Big-To-Fail banks be broken up.  But he goes further than that.  He wants to limit FDIC coverage to commercial banking operations only; anything else - securities trading, for example - would not be covered by you and me.  His reasoning is also based on the fact that the TBTF banks have been reluctant to lend.  Community banks (those with less than $10 billion in assets) hold more than half of the nation's small business loans, yet have less than 20% of our banking assets.  Another interesting factoid: Of the 5,600 commercial banks in the U.S., the twelve largest control 69% of the banking assets.
