This entry documents Patriotic Millionaires UK — a nonpartisan network of British millionaires that explicitly seeks to ‘‘leverage the voice of wealth’’ to end extreme wealth, push tax reforms, and secure proper public investment — included because it exemplifies wealthy individuals using their agency collectively to advocate systemic economic change; this directly supports the book’s Chapter “Your Worth And Power of the Collective” in PART 1: The Purposeful Investor by showing how high‑net‑worth actors can amplify collective action to challenge inequality and promote policy reform rather than relying solely on private philanthropy.
