From economist Tyler Cowen:
"By the estimates of Gregory Clark, economic historian at the University of California at Davis, English real wages may have fallen about 10 percent from 1770 to 1810, a 40-year period. Clark also estimates that it took 60 to 70 years of transition, after the onset of industrialization, for English workers to see sustained real wage gains at all.
If we imagine the contemporary U.S. experiencing similar wage patterns, most of us would expect political trouble, and hardly anyone would call that a successful transition. Yet that may be the track we are on. Median household income is down since 1999, and by some accounts median male wages were higher in 1969 than today. The more pessimistic of those estimates are the subject of contentious debate (are we really adjusting for inflation properly?), but the very fact that the numbers are capable of yielding such gloomy results suggests transition costs are higher than many economists like to think."
