I never said "no carpenter" tries to solve mental problems for mentally troubled people. I said it's fine if "a carpenter" just focuses on carpentry instead of people. Of course some carpenters can focus on both, that's great. But it's not everybody's job. This is just a factually accurate statement about the world. Every single person on this planet does not have the same job.

Everyone shares many jobs, like clothing themselves, breathing, eating, and using toilets.

Being a carpenter is not the only job a carpenter has

Everyone needs to do the "job" of "breathing", yes.

Everyone does not need to do the job of "sheltering mentally unstable people", no.
