James Pethokoukis explains for National Review Online readers why it would make more sense for President Obama and his allies to focus on job creation, rather than income inequality.

Before the Great Recession, there were 122 million full-time jobs in America. Now, four and a half years into the Not-So-Great Recovery, there are still just 118 million full-time jobs in America. That, despite a labor force that is 1.6 million larger and a non-jailed, non-military adult working-age population that is 14 million larger. To have the same share of civilian, noninstitutional adults working today as back then would require some 11 million additional full-time jobs.

Given the critical role of meaningful work in climbing the opportunity ladder and creating personal happiness, filling that jobs gap should be the defining challenge of the last three years of Barack Obama’s presidency. But it is not. Evidence: Team Obama’s sanguine reaction to the recent Congressional Budget Office report on anti-work effects of Obamacare. The CBO reported that “more than 2.5 million people are likely to reduce the amount of labor they choose to supply to some degree because of the [Affordable Care Act],” three times more than in an earlier forecast.

Who are those people? We don’t exactly know. Some of those working less or exiting the labor force entirely are older Americans who can retire early from a physical job. Others are moms working only because their hubbies don’t have employer-sponsored insurance. But another group is abandoning work only because the Obamacare nudge of high effective marginal tax rates makes it financially smart, at least in the short term, to do so.

What we do know is that the CBO sees slowing growth in the labor-force supply as a long-term drag on economic growth. And so does the White House. As its economists state in last year’s administration budget proposal: “In the 21st Century, real GDP growth in the United States is likely to be permanently slower than it was in earlier eras because of a slowdown in labor force growth initially due to the retirement of the post-World War II baby boom generation, and later due to a decline in the growth of the working age population.”

Shouldn’t news that Obamacare worsens that depressing trend be at least mildly provocative to the authors of health-care reform? Apparently not — nor to the rest of the 0.000001 percent who will continue to offer false talking points about how income inequality hurts economic growth and reduces upward mobility.
