Why Not Have Your Auto Repairman Perform Your Surgery?

The ethical auto repairman would never ever engage in surgery on a human being, since he knows he is not qualified to do so. Government and the economy are two very, very, very different kinds of things. But politicians are like an auto repairman who thinks, "well, both the cars I work on and the sick person here have bodies, so I might as well give it a shot." We'd put that person in prison, if not a mental hospital. But we keep electing politicians and giving them high pay to boot for thinking and acting in exactly the same way.
