Anyone with a small business who's tried to get credit in the past few months can certainly attest to the fact that lending has slowed. Small businesses around the country have reported that they can't make payroll because their credit lines have been slashed on short-term loans or credit cards. This only adds to the number of people laid off.

By converting the loans to the banks into equity, the Obama administration would have the largest voting stake in many of the big banks. Maybe this will finally get them to rethink bonuses and perks and instead find ways to unfreeze the credit markets. For example, the administration's conversion of Citigroup's loans gave it about a 36 percent stake in the bank.

Some critics wonder whether this is a back door to nationalization. The administration says that converting the preferred stock to common stock is the cheapest way to go. They won't have to contribute any additional cash but it could increase the capital of big banks by $100 billion or more.

But the big question will come when the U.S. has to vote those new common shares. Will there be a conflict of interest when the government looks for ways to maximize the value of the shares held on behalf of taxpayers? Is this attempt to save money a path down a slippery slope to bank nationalization? Is that better than letting some of the zombie banks fail and starting a new banking system without all the baggage?
