National Defense, Keynesianism, or Just Pure Rent‐​Seeking?

Sen. Johnny Isakson (R-GA) is fighting hard to maintain production of the F-22 Raptor fighter jet, which happens to be made by Lockheed Martin in Marietta, Ga. But Isakson insists that he's not fighting for the plane just because it's made in Georgia. No, he tells NPR, it's important to recognize that it's actually made by 90,000 workers in 49 states, and you don't want to lose those jobs at a time of high unemployment.

In a letter to President Obama, he spelled out his argument, albeit with slightly different numbers:

Over 25,000 Americans work for the 1,000+ suppliers in 44 states that manufacture the F-22. Moreover, it is estimated that another 70,000 additional Americans indirectly owe their jobs to this program. As we face one of the most trying economic times in recent history it is critical to preserve existing high paying, specialized jobs that are critical to our nation’s defense.

To be sure, Isakson does insist that the plane is vital to national security, an argument that Defense Secretary Robert Gates and Cato's Chris Preble challenge. But it doesn't say much for Republican arguments against President Obama's wasteful spending when Republican senators argue that we should build a hugely expensive airplane as a jobs program.
