Achieving shorter working days was the most consistent socialist demand in the 19th and early 20th century. We went from 12 hours, to 10 hours, to 8 hours.
I've seen old propaganda calling for 6 hours, sometimes even 4 hours, so what happened there?
With our staggering advances in technology and high automation factor, I don't understand why shorter work hours weren't achieved by now. Why did the fight for the 6 hour work stop?
