America prides itself on being the country of economic mobility, a place where your station in life is limited only by your ambition and grit. But changes in the labor market have shrunk the already slim odds of launching yourself from the mailroom to the boardroom. For one, the job market has bifurcated, increasing the distance between good and bad jobs. Working harder and longer will not translate into a promotion if employers pull up the ladders and offer supervisory positions exclusively to people with college degrees. Because large companies now farm out many positions to independent contractors, those who buff the floors at Microsoft or wash the sheets at the Sheraton typically are not employed by Microsoft or Sheraton, thwarting any hope of advancing within the company. Plus, working harder and longer often isn’t even an option for those at the mercy of an unpredictable schedule. Nearly 40 percent of full-time hourly workers know their work schedules just a week or less in advance. And if you give it your all in a job you can land with a high-school diploma (or less), that job might not exist for very long: Half of all new positions are eliminated within the first year. According to the labor sociologist Arne Kalleberg, permanent terminations have become “a basic component of employers’ restructuring strategies.”
