At the Hit and Run blog, Tim Cavanaugh bewails economic illiteracy:
It’s “very hard to fine-tune an economy” using any tools. That seemed to be a clear lesson of the twentieth century workers’ paradises, and it is implicit when politicians claim (usually following up with a “but”) that the free market is the least-bad system for creating wealth. Spending and taxes can, however, have very destructive effects, and the best way for government to further an enterprise is by the alacrity with which it gets out of its way. As the Clinton-era example shows, you can have a boom even if you just slightly reduce the rate of spending growth. That’s not fine-tuning, it’s slightly easing the heavy hand of the state. The Post’s rhetorical question leaves out such options as “Did they screw it up?” or “Did they do too much?”
You get to this level of fantasy not by knowing too little economics but by knowing too much, by being persuaded that the same math you use when you shop around for bargains or balance your checkbook does not apply at the level of the macroeconomy. Unfortunately, Keynesian logic is like Videodrome: Once exposed to it you can never get rid of it, no matter how much trouble it causes. Nobel Laureate Paul Krugman recently claimed that brisk sales of the iPhone 5 will spur economic growth, thus proving the broken-window theory of economics. In fact, it’s the opposite: People who buy the new phone think it will add value to their lives, not replace an equal amount of value that has been destroyed. As the Apple maps fiasco, the purple glare controversy, and this Jimmy Kimmel video suggest, they may be wrong about that. But that Krugman (who last year called for a hoax invasion by space aliens to spur spending) is down to such a transparently absurd argument suggests the time has never been riper to jettison both the new and old Keynesianism.
Just don’t look for either presidential candidate to do that. Right now the big question is whether Mitt Romney or Barack Obama will use his presidential job-creating powers to create more jobs. Mitt Romney is promising to create 12 million jobs, which strikes me as a strategic error. All Obama has to do is promise to create 13 million jobs and he’ll obviously be the better candidate, because that’s a lot more jobs.
