He's Been a Costco Cashier for 40 Years. Now He's a Millionaire.

Costco’s enduring success stems from a business model that treats labor as a strategic investment rather than a cost to be minimized. By offering competitive wages, robust health insurance, and retirement benefits, the company maintains an employee turnover rate of just 7%, significantly lower than the 60% industry average. This stability fosters a "virtuous cycle" where experienced, loyal staff provide superior customer service, driving membership renewals and consistent growth. Reporter Sarah Nassauer highlights that this approach, rooted in the philosophy of founder Sol Price, enables rank-and-file employees like 40-year veteran Tony Barzar to build long-term financial security. While this model requires significant capital and resistance to short-term investor pressure, it proves that prioritizing employee well-being can coexist with high corporate profitability, offering a rare, sustainable alternative to standard retail labor practices.
