As he dives into the Presidential race, creationist Texas governor Rick Perry is trumpeting the alleged economic “miracle” in his state and claiming it as a victory for conservative policies. But are Perry’s claims honest? Of course not: The Texas Unmiracle.

What you need to know is that the Texas miracle is a myth, and more broadly that Texan experience offers no useful lessons on how to restore national full employment.

It’s true that Texas entered recession a bit later than the rest of America, mainly because the state’s still energy-heavy economy was buoyed by high oil prices through the first half of 2008. Also, Texas was spared the worst of the housing crisis, partly because it turns out to have surprisingly strict regulation of mortgage lending.

Despite all that, however, from mid-2008 onward unemployment soared in Texas, just as it did almost everywhere else.

In June 2011, the Texas unemployment rate was 8.2 percent. That was less than unemployment in collapsed-bubble states like California and Florida, but it was slightly higher than the unemployment rate in New York, and significantly higher than the rate in Massachusetts. By the way, one in four Texans lacks health insurance, the highest proportion in the nation, thanks largely to the state’s small-government approach. Meanwhile, Massachusetts has near-universal coverage thanks to health reform very similar to the “job-killing” Affordable Care Act.

So where does the notion of a Texas miracle come from? Mainly from widespread misunderstanding of the economic effects of population growth.
