Schmitt, John.
Over the last two decades, high – and, in some countries, rising – rates of low-wage work have emerged as a major political concern. According to the Organization for Economic Cooperation and Development (OECD), in 2009, about one-fourth of U.S. workers were in low-wage jobs, defined as earning less than two-thirds of the national median hourly wage (see first figure below). About one-fifth of workers in the United Kingdom, Canada, Ireland, and Germany were receiving low wages by the same definition. In all but a handful of the rich OECD countries, more than 10 percent of the workforce was in a low-wage job.
