When everyone is invested into society, we have incentives to defend the status quo, thus making our society stable. In the next generation or two we'll get to see what happens when half of the men of the nation don't own anything of substance and have no meaningful connections to society.
Yeah there’s a secret dark opposite of NIMBY - WGASA (who gives a shit anyway) and that can end up much worse in the long run.
Part of the problem for communities starts when not all participants live in the community - if the grocers and workers and police are “imports” from the suburbs or other areas you start to get divergent goals and WGASA starts to take hold.
Homeownerism sounds like a regional form of nationalism where an us Vs them conflict is actually the point. The problem is that once you understand the problem as a politician the only thing you can do is do even more nationalism by including the formerly excluded and doing an us vs the world because not having an enemy and cooperating with everyone else is unimaginable.
