> people don't need to clean toilets for a living,

I swear to you, our janitor is the happiest, hardest working person in the building. Everyone looks up to him. But I can totally see where he couldn't work at McDonald's, let alone do QA runs on lab systems (a lab tech's job), or diagnose disease. And I think a genuine source of his happiness is having a job. Basic income doesn't solve the problem of feeling valued.
