CEO Doug McMillan's decision to raise worker pay by 90% was key to Walmart's resurgence. This investment in people lowered turnover, improved service, and attracted new customers, ultimately quadrupling the stock price and proving a vital strategy against competitors like Amazon.

While Amazon masters digital and Costco dominates physical retail, Walmart is uniquely succeeding by becoming fluent in both. By seamlessly integrating its massive physical footprint with a strong e-commerce and app experience, Walmart has created a powerful 'omnichannel' model that pure-play competitors struggle to replicate, driving its stock to all-time highs.

Reflecting on Walmart's multi-year transformation, CEO Doug McMillan identifies the most common leadership pitfall: delaying actions you instinctively know are right. He advises leaders to trust their gut and move quickly, as organizations are often more capable of handling rapid change than perceived.

Walmart's primary view of AI is offensive, focusing on growth opportunities like creating a personalized, multimedia e-commerce experience. This shifts the narrative from AI as merely a defensive efficiency tool to a strategic growth driver, fundamentally changing how people shop.

The ultimate differentiator for CEOs over decades isn't just product, but their skill as a capital allocator. Once a company generates cash, the CEO's job shifts to investing it wisely through M&A, R&D, and buybacks, a skill few are trained for but the best master.

The AI job impact conversation has moved beyond tech. Walmart's CEO expects AI to change every job and plans for flat headcount over the next three years, even while growing the business. This signals a new mainstream corporate playbook focused on productivity over job creation.

To manage an overwhelming list of necessary business changes, Walmart's leadership began by clearly articulating what would remain constant: its core values. This provided a stable foundation, making the subsequent, widespread transformation feel more manageable and less threatening for employees.

By paying staff up to 150% above the industry average, Trader Joe's creates a significant operating advantage. This investment leads to extremely low turnover (one-tenth the industry average), reducing hiring and training costs while fostering a knowledgeable, happy workforce that improves the customer experience.

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.
