The official rate of unemployment in America has plunged to a remarkably low 3.8%. The Federal Reserve forecasts that the unemployment rate will reach 3.5% by the end of the year.

But the official rate hides more troubling realities: legions of college grads overqualified for their jobs, a growing number of contract workers with no job security, and an army of part-time workers desperate for full-time jobs. Almost 80% of Americans say they live from paycheck to paycheck, many not knowing how big their next one will be.
