Let's call it Weaponized Governmental Failure. It's the single most explicative factor in the breakdown of American political consensus in the 21st century, even though it's been around since the latter part of the 20th century.

The simple definition of Weaponized Governmental Failure is this: it's the deliberate refusal to perform the basic tasks of urban governance for a specific political purpose.

The crime and the graft and the potholes and the bad drainage, not to mention the spotty trash collection or nonexistent snow shoveling, aren't incompetence. In fact, none of what you see in the American public sector is incompetence. The people responsible for it are quite highly educated and well-trained in their craft. You just need to understand what their craft is.

It's a choice to do a poor job with the more mundane tasks of running a city, and an educated and purposeful choice at that. If you do those things effectively, after all, what you will get is middle-class voters moving in. Middle-class voters tend to choose to live in places where they can expect to get actual value out of their tax dollars — good roads, safe streets, functional drainage, decent schools, a friendly business climate, and a growing economy, among other things — and those things are hard to produce when you govern the way the Left does.

Put a different way, middle-class voters are a pain in the ass.

They want lots of things that make for unrewarding grunt work for a mayor, and a Democrat blowhard like a Mitch Landrieu or Ted Wheeler of Portland would rather spend his time on vacuous cultural aggressions like "social change" and offering wealth redistribution and excuses for the bad personal habits that cause so many people to be poor.
