The situation in the late 19th century was a historical aberration and workers neither since nor previously worked that many hours. Note also that in that period, Western society was full of day laborers, hobos and other chronically underemployed people. That is how capitalists could force workers into working insane hours at low pay. Because if they didn't want to do it, then there were thousands of others that were willing to. And importantly, most women were not employed which they are now. Given these factors it is not certain that the average
person worked harder in the 19th century than the average person does today. The average
factory worker certainly did, but that is different.
I don't get what is with these snarky replies all over Hacker News these days. His point was that people work a lot. Quarreling over whether some people some time during history has worked even more is missing it.
