UPDATE: The item text here focuses on 1973 as the trend start; Nixon's second term. But even though while the divergence held through the "stagflation" years of Ford and Carter it did not precipitously diverge. What the chart clearly shows is the divergence had not taken off like hellfire until 1980 onward and we all know that was Reagan, Bubba, and the Bushes in the oval office when the situation worsened tremendously - wages even for a while decreasing as productivity rose steadly. So blame Reagan most, the Republicans in toto, and the Bubba triangulation BS which was nothing more than Republicanism in drag.
