but I suspect USA slumlords have been subject to gentrification too. Because every city has them, developers and landlords who are too big to fail because they provide the housing and jobs that keep things moving. In poor areas some never fix anything. In revitalization, they do things like this guy, begging for every last dollar from government. It's all because of the tax code, federal, which was written to make sure there are houses and jobs by providing tax write offs on debt and incentives. My analysis loosely connected to reality, but you get the idea.
