Well, you painted it as at least partially a race issue in your previous comment. If it's not a race issue, you shouldn't reference race in whatever point you're trying to make, unless you're just trying to be incendiary for its own sake. And if you can't make a point without being incendiary about it, realize that whatever point you're trying to make is almost certainly objectively wrong, or perhaps your philosophy is more about maintaining a romanticized self-image than actually trying to make the world a better place or even acquiring basic wisdom about anything.

Bomb (or brick) throwing is trivially easy and makes the thrower feel like a badass without actually helping anyone. Actually trying to look at all sides of a complicated issue, figuring out what should be done about it, and trying to make a difference is hard, thankless, and humbling. It will make you feel stupid and inadequate for the task, because it's hard and it's worth doing. People who care about those things don't have your comment history; people who are feeding intellectual conceits do.

Wealthy people move in, raise property values, spur local economy, but displace lower-income families and the kinds of independent marginal businesses that served them. Or, wealthy people move out, property values plummet, services are slashed, land goes vacant, crime skyrockets, and kids can't safely get to school anymore.

What is the middle ground? I'm asking seriously. Imagine you were a city planner or the mayor of SF or Detroit or BDFL of California or whatever. What's your plan?
