Wages for American working men got a double whammy during the last fifty years. First, starting in the late 1960s, American women entered the paid workforce as never before. This added significantly to the supply of labor in the American workforce. Secondly, just as the American labor market had started to move beyond the economic shock of increased entry of women into the workforce, the uptick in globalization – easier mobility of capital and labor across national borders – effectively increased the supply of labor competing with U.S. workers a second time. Many of these workers were willing to work for wages significantly below wages for American workers. There are other causes as well, but these factors certainly contributed to stagnating wages for working men in the U.S. over the last 50 years.
But this is not simply a story of loss; there are tradeoffs.
