“Growth in median incomes during this period tracked nearly perfectly with per capita GDP. Three decades later, median household income had increased to about $61,000, an increase of just 22 percent. That growth, however, was driven largely by the entry of women into the workforce. If incomes had moved in lockstep with economic growth – as was the case prior to 1973 – the median household would today be earning well in excess of $90,000, over 50 percent more than the $61,000 they do earn.”
