Most of the earth's inhabitants work to get by. They work because they have to. They didn't pick this or that kind of job out of passion; the circumstances of their lives did the choosing for them. Loveless work, boring work, work valued only because others haven't got even that much, however loveless and boring - this is one of the harshest human miseries. And there's no sign that coming centuries will produce any changes for the better as far as this goes.
