David Cain noticed his spending habits changed when he returned from many months backpacking around the world:

One of the most surprising discoveries I made during my trip was that I spent much less per month traveling foreign counties (including countries more expensive than Canada) than I did as a regular working joe back home. I had much more free time, I was visiting some of the most beautiful places in the world, I was meeting new people left and right, I was calm and peaceful and otherwise having an unforgettable time, and somehow it cost me much less than my humble 9-5 lifestyle here in one of Canada’s least expensive cities.

It seems I got much more for my dollar when I was traveling. Why?
Later on he gets to the antiquated 40-hour work week bullshit we still have in the West:
The eight-hour workday developed during the industrial revolution in Britain in the 19th century, as a respite for factory workers who were being exploited with 14- or 16-hour workdays.

As technologies and methods advanced, workers in all industries became able to produce much more value in a shorter amount of time. You’d think this would lead to shorter workdays.

But the 8-hour workday is too profitable for big business, not because of the amount of work people get done in eight hours (the average office worker gets less than three hours of actual work done in 8 hours) but because it makes for such a purchase-happy public. Keeping free time scarce means people pay a lot more for convenience, gratification, and any other relief they can buy. It keeps them watching television, and its commercials. It keeps them unambitious outside of work.
It’s amazing how such obvious observations can be so eye-opening (and depressing).
