The Walton Family — $260B+ Combined

The Walton family's $260B+ combined fortune exceeds the entire net worth of the bottom 40% of Americans, a stark inequality gap that no other clan on this list replicates with such scale. Walmart, which built their wealth, has historically paid wages so low that one in five of its U.S. workers qualified for Medicaid or food stamps, representing a subsidy of roughly $6.2 billion annually from taxpayers. Compared to the more diversified Koch network, the Waltons' fortune is singularly tied to labor cost minimization, with an average store wage of just $14.26 per hour, undercutting the retail industry average by over 20%.
