Honestly, from everything I’ve seen in my life, I tend to worry a lot more about people that don’t work and don’t have the financial need to work. They often seem to fall into mental health troubles. The healthiest people I do know that didn’t need to work, ended up doing so anyway.
That doesn’t necessarily mean that the job they pick should maximise money. The benefit of having lots of money, is that you can choose a job that is fulfilling for you that might not fall under the category of jobs that cover your expenses. Or maybe your dream job required so much up-front investment that you couldn’t get into it in the first place, like car racing.
I think that the country makes a huge difference here. It’s of course naïve to assume that you specifically had the choice, but there are most certainly places where that choice does genuinely exist.
The working population in my own country averages 27.7 hours per week. Excerpt from that source:
Now, you could of course remark that this age group is quite broad (15-74), but for people aged 20-64, it is still 32.1 hours. Of course, there is still the man/woman split, but this does not account for everything.
But of course not everyone lives here! So indeed we should be mindful that not everyone has this choice, and even in this country, there are plenty of people who do not have the luxury to be able to work part time.
