For the life of me, I don't understand why we don't replace rent control with means-tested cash grants if we really care about displacement (and pay for it out of a Land Value Tax, but that can be an orthogonal issue). The way we have it now, we're screwing arbitrary renters (including poor ones) that happen to move between apts more often, to pay arbitrary renters that happen to move less often (including rich ones). I don't understand how anyone could say it's good policy with a straight face.
