But you replied to my post saying your job is most definitely useful and my argument is that it’s not.

I don’t disagree there are certainly things each of us on this planet think is good or useful but in my opinion that’s the problem. How do you get a collective group of different humans to agree what that is. Capitalism with all its faults solves this problem pretty nicely. It’s not perfect but as far as I know it has been the best system so far.
