Granted, these figures to not cover the last recession, but we've got a lot of ground to lose before your "theory" begins to hold water.
Average hourly earnings in private, nonagricultural business increased in real terms by about 16 percent during the past 40 years, but professionals did better: physicians, for example, enjoyed an increase in real earnings of 33 percent in the same period. One way of looking at the benefits of rising productivity is to compare various family income groups. The top 5 percent of families had an increase in income of 129 percent in real terms from 1960 to 1998, while the middle fifth had an increase of 54 percent and the bottom fifth only 38 percent. Family income went up not only because productivity was greater for other reasons, such as the increasing number of wives taking jobs outside the home. The average real income of working Americans, as the chart [at the top of the thread] shows, increased beginning in 1995--undoubtedly made possible by the spurt in productivity over the same period.
