If you were in contact with planet Earth, you would realize the digital revolution started in the 1970's and that was the cause of the sharp increase in productivity.
Ah, I see. So, the innovations of mass production, of mechanization, of commercial flight, of communication, and of better healthcare just didn't do anything to increase production of labor faster than wages. Then, the digital revolution came along, and finally something increased the production of labor faster than wages.
It makes sense, if you don't think about it. I suppose a lobotomy and a few hours on zero-hedge might help me understand.
