The Thread · Issue #10 · August 10, 2026The housing market didn't just get expensive — it stopped moving. This issue traces why: a building shortage that never recovered, a rate-lock freeze that's uniquely American, and a downsizing math that keeps owners in place while a whole generation waits outside.
