I live in a city. That is not going to solve anything. Efficiently run utilities is probably the quickest solution. The majority of people cannot remove themselves from society.

I get it. I can only control what I can. I live in the mountains in Switzerland. I work with what I have around me.
Privatising utilities for better efficiency requires that you have reliable and trustworthy companies/people to run it. Do you believe such people exist in your city without running over people for profits?
