I’ve been to a corporate training session at Disneyland where they talked about keeping the park clean. Broken Window theory is part of it, so they take active steps to keep the park clean. For example, they studied how far people were willing to walk before they would just drop their trash on the ground and then put trash cans within that distance of each other. They have employees whose job it is to sweep constantly, but every single employee takes pride in the park and picks up trash lying around. If one lightbulb is out they replace all the lightbulbs to reduce the broken window effect and keep the appearance that they aren’t constantly fixing things.

No city that I know of takes this approach. I’ve heard anecdotally of some cities striving for it. But I can’t imagine it being at the same level as the Disney culture
