> Average hours worked is more or less monotonically decreasing since the start of the industrial revolution
Although that is true when comparing the start of the Industrial revolution and now, people worked less hours before the Industrial revolution [1]. Comparing the hours of work per year in England between the 17th century and the 19th century, there has been an increase of 80%. Most interestingly, the real average weekly wages over the same time period have slightly decreased, while the GDP has increased by 50%.
No, on average people in 1600s England (who were overwhelmingly peasants) worked almost all daylight hours, 6 days a week - perhaps 3000 hours a year. It's simply not possible for the hours worked to have increased a further 80% from that baseline.
Also most labour was not wage labour in the 17th century, so you need to be careful looking at wages. Especially comparing the the 19th century since there was a vast expansion of wage labour.
