Only 25.2 percent of American workers have a job that pays at least $16 per hour and provides health insurance and a pension, according to a new study by the Center for Economic and Policy Research.

The report, "How Good is the Economy at Creating Good Jobs?" found that between 1979 and 2004 the share of American workers in good jobs remained unchanged at about 25 percent, despite strong economic growth over that period. (The report defines a "good job" as one that offers at least $16 per hour or $32,000 annually, employer-paid health insurance and a pension.) In the last quarter century, the U.S. workforce has become older, more experienced and better educated, but 75 percent of workers are still struggling in jobs that do not provide health insurance, a pension and solid middle-class wages.
