The 20th-century view of shareholder primacy is flawed. By focusing first on creating wins for all stakeholders—customers, employees, suppliers, and society—companies build a sustainable, beloved enterprise that paradoxically delivers superior returns to shareholders in the long run.

Great companies survive not because of a founder's continued presence, but because the founder codified a culture and operational DNA that outlives them. Companies like Home Depot and Amazon continue to thrive because their core principles are deeply embedded and replicable.

A noble mission statement, like Johnson & Johnson's famous credo, is powerless against the pressures of shareholder primacy. To be effective, a company's purpose must be structurally embedded in its corporate charter and governance, giving it legal and operational teeth.

Unlike startups, institutions like CPPIB that must endure for 75+ years need to be the "exact opposite of a founder culture." The focus is on institutionalizing processes so the organization operates independently of any single individual, ensuring stability and succession over many generations of leadership.

Public companies, beholden to quarterly earnings, often behave like "psychopaths," optimizing for short-term metrics at the expense of customer relationships. In contrast, founder-led or family-owned firms can invest in long-term customer value, leading to more sustainable success.

A sustainable competitive advantage is often rooted in a company's culture. When core values are directly aligned with what gives a company its market edge (e.g., Costco's employee focus driving superior retail service), the moat becomes incredibly difficult for competitors to replicate.

Charlie Munger prized 'win-win' systems, and Costco is the prime example. By offering clear value to all stakeholders—low prices for customers, reliable partnership for suppliers, high wages for employees, and steady returns for investors—Costco creates a self-reinforcing, durable competitive advantage that is difficult to replicate.

Both companies leverage their independent ownership to make long-term, values-driven decisions that might be challenged by public market investors. This structure provides the freedom to prioritize purpose over immediate profit, such as restraining growth or making bold political statements.

The story of Costco's success versus FedMart's failure highlights two essential elements. A company needs the 'ethos' of putting customers first, but it also needs the 'integrity' of a corporate governance structure that protects its mission from short-sighted investors and outside meddling.
