The bailout’s backers argue that a GM bankruptcy would hold as much systemic risk for the real economy as a huge bank failure, but those risks are overstated. Chapter 11 is a well-established tool for financial restructuring. It is not tantamount to collapse or liquidation. If White House economist Ed Lazear is worried that no one will accept a car warranty from a bankrupt company, then Congress can address that specific problem rather than write an open-ended check. Chapter 11 could well offer a speedier resolution to the auto makers’ plight than a slow-motion, politically infected catastrophe that could easily cost $125 billion or more.
