When I was young and fresh out of college, I earned £8000 per annum and attempted to support a non-working partner and a small child. The idea of time vs money was irrelevant. I did not have enough money to live on. I would work as much as possible to get more money, and it still wasn't enough to live on. Fast forward to now where I have enough money not to bother about budgeting day to day and there is still enough…
There is, however, also a large group of people who could have more free time but choose to work more because they prefer to own more stuff to having more free time.
I work an 80% job (4-day work weeks) because I have reached the point where I don't really need more money. I don't consider myself rich, but with my spending patterns I don't need to worry about a daily budget anymore, and I have cash leftover to save every month. A lot of people are genuinely surprised by this decision, even though they work the same kind of job as me and therefore many of them likely have a similar financial situation.
