I'm glad you said it, I read this and it bothered me. What about "steal a living" or "hunt a living" or "create a living". I think the missing word is "for" you do these things "for a living", that is to say, to get the resources you need to remain alive.

That said, I do get the message. The idea of living in a world so abundant but unfair that you live or die by what you can produce for someone else is pretty wrong
