What do a 1970 psychology experiment and the 2008 housing crash have in common? In Episode 6 of Built to Divide, Dimitrius Lynch traces how social identity theory—the instinct to form “us vs. them” groups—became a political weapon that helped sell a bipartisan push for mass homeownership, weaken skepticism, and pave the way for subprime mortgages, mortgage-backed securities (MBS), CDOs, and a crisis engineered by incentives.We move from NAFTA-era globalization and Peter Drucker’s “core competencies” mindset, to the dot-com bust, Fed rate cuts, and the explosion of “stated income” lending. The episode spotlights Washington Mutual (WaMu)—from community-friendly bank to shareholder-driven mortgage machine—then follows the collapse, the scapegoating of low-income borrowers, and the rise of institutional investors turning foreclosures into portfolios. A story about housing, finance, and the narratives that keep us divided—even when the math says we share the same stakes.Episode Extras - Photos, videos, sources and links to additional content found during research.Episode Credits:Production in collaboration with Gābl MediaWritten & Executive Produced by Dimitrius LynchAudio Engineering and Sound Design by Jeff Alvarez
