arxism was supposed to have brought about a lot of positive changes, including the creation of a classless society, where everyone lived in peace. To these ambitious goals can be added substantial reduction in the amount of labor required from the proletariat.
As Rodney G. Peffer from the University of San Diego put it in his 2014 book Marxism, Morality, and Social Justice:
Marx believed the reduction of necessary labor time to be…an absolute necessity. He [claimed] … that real wealth is the developed productive force of all individuals. It is no longer the labor time but the disposable time that is the measure of wealth.
Little did the German economist know that free markets would achieve his objective with aplomb.
The number of hours worked per day has fluctuated throughout human history. Based on their observations of extant hunter-gatherer societies, scholars estimate that our foraging ancestors worked anywhere between 2.8 hours and 7.6 hours per day.
