Personally I've thought government and democracy both work best the more the local they get. The problem with that is there's just more inherent power when you have power over larger groups of people. If you have a fix or even a "fix" for a problem or even a "problem" then the temptation to implement it over the greatest number of people you can is extremely high. If it's a good idea (and why would do it if it wasn't?) why do it just for the city? Why not do it for the state or the country? And once you're doing something for (or to) everyone, how can you test to see if stopping that is a good idea?
