@ChrisWere My answer would be, which societies have the lowest proportion of hungry or homeless people? “Great artists steal.” Have an idea to reduce homelessness/hunger even less? Try it on a small scale; if it works, try scaling it up.
And yes, people will try to sabotage it for selfish reasons. Are there societies where that kind of sabotage is less common? If so, learn from them. Ideas for reducing that problem? Trial them and see if they help.
