The February employment numbers, released today by the U.S. Department of Labor, suggest modest improvement in the labor market. The unemployment rate ticked down to 8.9 percent and payroll employment jumped 192,000, the largest increase since the Census-boosted hiring last May.
Long-Term Earning Trends
The American Dream promises that every generation can achieve more than the previous generation—but this has not been the case in recent decades. As noted in a previous jobs blog, American men have had a particularly hard time adjusting to the dynamics of a new world economy.
It has been widely observed that over the last several decades wage earnings for the median full-time American male worker have stagnated. For example, in 2009 the median full-time male worker aged 25-64 brought home $48,000—roughly the same as in 1969 after adjusting for inflation. 
At the same time, there has been a sharp decline in employment rates for men, particularly lower-skill men with less than a college degree. Today, only 66 percent of American prime-aged men hold full-time jobs, down from 80 percent in 1970. Further, the reduction in work is greater for the less-educated (79 percent of high-school graduates held a full-time job in 1970 versus 57 percent today.)
Three shifts in the employment landscape are largely responsible for the decline in full-time employment. First, men with jobs are less likely to hold full-time jobs. In 1970, 86 percent of jobs held by prime-age male workers were full-time jobs, compared with 81 percent today. Second, between 1970 and today, the share of men without any earnings at all increased from 6 percent to 18 percent. Third, 2.2 percent of these prime-age men now live in institutions—primarily prisons—and no longer appear in most labor-market statistics.
Thus, the pool of full-time workers has shrunk at the same time that the median wages of full-time workers has stagnated. Why is this important? It means that the statistics about the stagnation of wages like those above are based on a comparison of very different groups of workers. Put plainly, the story of the stagnation of wages is based on a comparison of apples to oranges.
When you compare apples to apples by looking on the experience of all men (rather than just the changing group of men able to find full-time work), the stagnation story has a different ending.
The below figure plots the median earnings based on all males aged 25-64, along with the more conventional plot that is based only on those men aged 25-64 that happen to work full-time.
This analysis suggests that earnings have not stagnated but have declined sharply. The median wage of the American male has declined by almost $13,000 after accounting for inflation in the four decades since 1969. This is a reduction of 28 percent!
The February Job Gap
In addition to the threat to workers of declining wages, the United States is still facing a severe job gap of more than 12 million jobs. The chart below shows how the job gap has evolved since the start of the Great Recession in December 2007, and how long it will take to close under different assumptions for job growth. The solid line, in particular, shows the net number of jobs lost since the Great Recession began. The broken lines track how long it will take to close the jobs gap under alternative assumptions about the rate of job creation going forward.
If the economy adds about 208,000 jobs per month, which was the average monthly rate for the best year of job creation in the 2000s, then it will take until June 2023—another 12 years—to close the job gap. Given a more optimistic rate of 321,000 jobs per month, which was the average monthly rate for the best year of job creation in the 1990s, the economy will reach pre-recession employment levels by May 2016—not for another five years.
 The median worker is the middle of the road—by definition, half of workers earn more than the median worker and half earn less.
