Legitimate economists often bristle at this kind of talk for good reasons. Discrete job calculations in a massive, dynamic U.S. economy are notoriously tricky and depend on all sorts of variables, many of which are disconnected from the policy or project at issue. Furthermore, many policies don’t increase or decrease jobs but instead change the types of jobs we have. Most fundamentally, economists know that labor is a finite resource, and so jobs are considered part of a project’s cost, not one of its benefits. If the government could magically develop and install a cross-country hyperloop (or whatever) without using any time, materials, taxpayer dollars, or workers, it’d be a massive win: Not only do we get the hyperloop (or whatever), but all the resources the project would have used could instead be deployed elsewhere in the economy, boosting overall output and growth.
Still, in the wake of the Great Recession—when unemployment and worker anxiety were high, job openings low, wages stagnant, and the labor market’s future uncertain—a political obsession with job creation was at least understandable to even the most curmudgeonly of economists. Yes, of course, jobs are technically a cost and all those numbers are silly, but, with millions out of work and businesses not hiring, one could be (mostly) forgiven for pandering to voters about the bajillions of “shovel-ready” jobs a government project supposedly “saved or created.”
