Well yes, of course. High-density housing provides a lot more good with a lot less bad than chemical refineries. Besides which, it's both factually wrong and in severely bad taste to imply that working-class people are a form of chemical pollution. Also, violent crime is at an all-time low, in dense cities as much as in rural suburbs right now. The whole view that dense housing somehow equals violent crime is decades out of date and largely only ever applied to deliberately-created black ghettoes in the first place.
