The number of days we work has nearly nothing to do with the technology available to us and everything to do with the relative power between labour and capital.
I rent a very basic one bedroom in an awful location which costs more than half my after tax salary, and a round trip to my office in Toronto takes 3 hours and $45 of public transit. The price of this unit has also increased by more than my salary every year for the past 3 years.
Here's hoping I get to be one of those people who can relocate from Toronto next.
Keeping up with the joneses is a big driver of long work weeks. Globalization also drives it. Scale drives it. Boredom drives it. It's complicated.
The takeaway message is: yes, the capital class are and have always been the main drivers of longer hours.
