Writing at National Review Online, Jim Manzi offers excellent arguments against the federal bailout of General Motors:
You can’t compare all of these net tax receipts (or more broadly, economic activity) to what would happen in “the world as it is today, minus GM.”
First, in the event of a bankruptcy, you don’t burn down the factories, erase all the source code on all the hard disks, make it illegal to use the brand name Chevrolet, and execute all of the employees. Others take ownership of the assets, and the employees go on with their lives. Some of these assets will be put to use generating revenues, profits, and taxes, and some of these former employees will get jobs or start businesses, and generate revenues, profits, and taxes. In order to measure the effect of the bailout over, say, five or ten years, you have to compare the actual taxes collected to what would happened over this same period in the counterfactual case where the bankruptcy was allowed to proceed. What owners would have bought the factories and IP assets, and what would they have done with them? What businesses would the former employees have started? Who would have moved to Arizona and retired? What new industry clusters will evolve in Arizona because of this transfer of people?
Second, some of the profit GM makes today would have been made by other companies that picked up some of the slack if the company lost market share after a bankruptcy. They would pay taxes on these profits, and as far as government receipts are concerned, money is money. How would auto industry structure evolve over time given whatever changes happened to the assets currently owned by the legal entity GM, or the employees currently paid by it?
Anybody who tells you they can answer all of these questions reliably is full of it.
And that doesn’t even start to get to the really long-run considerations of what effects this has on rule of law and moral hazard (or if you want to make the case for the bailout, social solidarity and degradation of the working class).
