Across all categories in September 2026, podcast conversations gravitated toward who really builds wealth, how they do it, and what kind of future that wealth is being created into. The Everywhere Millionaire stands out as a clear outlier, surfacing across macro, investing, and personal finance shows as a rigorous, story-driven examination of America’s hidden affluent and the tax and policy structures around them—signaling intense interest in the realities behind “millionaire next door” narratives. Classic personal finance and investing titles like Rich Dad Poor Dad, The Millionaire Next Door, One Up On Wall Street, and the new Stock Picker point to a continued focus on self-directed investing, temperament, and long-term wealth-building. In parallel, Superintelligence, The Fourth Turning, and even the enthusiasm for Andy Weir’s The Martian and Project Hail Mary reflect concern with technological and geopolitical inflection points, and with resilience and ingenuity in uncertain environments.
