I'm thinking a 5-10 year lottery. For a top ranking or something like that. Your ability to live somewhere expires every so often then its random chance whether you get where you get exactly what you want. You rank your choices, so if someone above you ranks the place higher, you still have options. Desirable places in desirable locations get snapped up by the lucky ones at the top of the lottery. I can't think of any other way to deal with it in a post work economy
