Perhaps my examples are not the best. Plumbers and cabinet makers are professions that pay well eventually. The point I was trying to make that people do indeed spend their free time doing thing what they do for a job.
Stating that craftsman do not work for money (and its benefits) is ridiculous.
This is the part that I just don't understand where both you and the grandparent post got from.This whole thread is about working for pleasure ONCE the income from that activity covers the cost of living. Again the quote from the original post is: "Once you have enough money to keep food in your belly and a roof over your head". Quote from the post above that is: "Yes, I work in imaging research, trying to bring about medical imaging progress, with hopefully useful results. I'm not at all motivated by profit. I just want enough money not to starve and enough funding to pay my students and equipment." (Emphasis mine).
No one that I can see has stated in this thread that anyone works for absolute free. We do not dispute that! Your bills needs to be covered first. But beyond covering your needs, profit need not be the motivation!
For example: You have a choice to stay doing a job you love, but only covers your expenses or do what you don't like, but earn triple the amount that you need. In BOTH cases you are NOT working for free! In BOTH cases your living expenses are covered.
What this thread is about is that choosing the former is better for your quality of life than the latter. This is the interesting and complex part that is being discussed. Not simplified "Be a hippy to be happy!" nonsense that you are reading into the discussion.
