JT, we've been over this before. You accepted the union propaganda, without questioning. The 40 hour work week was the result of work/motion studies and Henry Ford. After 40 hours, human attention span and energy begins to drop. At 50 hours, there is significant loss to the company. Ford desired the 40 hour work week because he could keep up to 3 shifts working and allow time for his employees to enjoy the product. He encouraged other industries to do the same.
The middle class grew in the US well before the advent of unions.
The middle class came from unions and FDR's programs. Before FDR, the "robber barons" gave us the depression.
The robber barons were the 1880s recession. JT, you don't know history, nor the cause of the depression -- government interference caused a recession to grow into the depression. We've been over this before. Time for you to see the doc, if your memory is fading like Hillary and Huma.
