Are renters not part of the community, or are you saying they don't know what's in their self-interest?
You haven't said a ton, but it seems like you're using "community" as code for home values. However, that might not at all in the best interest for many in the community. It's particularly of importance to home-owners. It might be to the detriment of renters.
Renters have less incentive to care for the commons because it’s much easier to move on. That’s just one example, understanding the concept of skin in the game and consideration of how it applies in this context allows easily finding many more.
You're just saying "the commons" instead of "the community" now. Are renters part of the commons? If so, what it means to care for the renters is part of what it means to care for the commons.
