Brian & Marion discuss the hottest trend that's showing up in cities from D.C. to Brooklyn to Durham, NC -- gentrification! They get into the difference between gentrification and revitalization, what your responsibility is as an individual to fight gentrification, and whether there are any communities out there who are actually getting it right. Marion also gets profane talking about The Sims, which is shockingly relevant; and Brian takes us on a history detour to 9th-century Ethiopia.
