Charlie Munger's core microeconomic lesson is to discriminate between when technology helps you and when it kills you. In a business with pricing power (brand, network effects, patents, switching costs), productivity gains stay with owners and widen the moat. In a commodity business, those same gains flow through to customers as lower prices and accelerate competitive destruction. The destination of the gain — owner or customer — is the single best signal of whether you actually have a durable advantage.
