Rick Santelli is right

Rick Santelli, CNBC

This morning I watched CNBC's Rick Santelli talking from the Chicago Board Of Trade.  His so-called, "Santelli Rant" has been watched on YouTube over a million times and his sentiments today, once again, represent the views of many Americans who believe in living within one's means -- it's how we were raised -- but we lack a microphone.

Rick Santelli was in fine form this morning while debating Steve Liesman.  The topic was banking reform and Mr. Santelli made a case for an elegantly simple cure -- raise the banks' capital requirements. 

Another CNBC commentator astutely chimed in that this is the same risk premium banks require when a homeowner has a marginal credit history -- the bank looks for more cash in the deal -- a bigger down payment to compensate for the risk of default.

Why can't we use the same mechanism to minimize chances of another banking meltdown?  Do we need new federal agencies, reams of new regulations, congressional hearings, class warfare speeches and on and on?  I realize that raising the amount of capital that banks must hold affects their profitability, but maybe it's a reasonable way to manage systemic risk.
