Of course, people have different personal situations that might result in them ending up at a job that's not in one of their particular areas of interest, but it's overly dismissive to say "the only possible true answer is to get a job", when in fact many candidates could get jobs at tens or hundreds of companies and are very selective about where they end up. We recently hired a candidate who took a sizable pay cut to work with us. I'm sure he could've gotten a meaningfully higher offer to work elsewhere, but ultimately he actually just believed in the long term value of what we were building, and that's valuable for both parties.
It is true that some people don't really care at all, but that actually seems to be the minority in my experience. I've had candidates answer me in the past with "to be honest, I saw a job listing and applied" when I asked them why they want to work at our company. I appreciated their directness, but ultimately if that's how they feel, it probably wouldn't be a good fit for either of us.
When I read your writing and you say things like
the purpose of the job does not make me sick
that makes me quite sad actually. You should aim much higher.
