I'm guessing those wages exclude benefits, because when you consider total compensation it actually reflects growth in productivity. Total employee compensation as a share of national income was 66 percent of national income in 1970 and 64 percent in 2006. This measure of the labor compensation share has been remarkably stable since the 1970s. It rose from an average of 62 percent in the decade of the 1960s to 66 percent in the decades of the 1970s and 1980s and then declined to 65 percent in the decade of the 1990s where it has again been from 2000 until the most recent quarter. http://www.nber.org/papers/w13953 http://www.nber.org/papers/w13953
