The United States economy is full of innovation. It has to be. Manufacturing industries that dominated the economy decades ago - textiles, televisions, even automobiles to a large degree - have moved overseas, where labor and materials costs are lower. Yet the U.S. economy, even during the pandemic and the current period of high inflation, has expanded to record levels. If U.S. corporations weren't innovating, creating new products (such as vaccines and AI) and services (such as Zoom calls) and moving into new markets, the domestic economy would not be growing, and capital would not be flooding into the country. The current high level of the U.S. dollar relative to currencies around the world attests to the confidence that global investors have in the durable and innovative U.S. economy.

Costco operates a membership-based, no-frills retail model, predicated on offering a select product assortment in bulk quantities at bargain prices. The firm avoids maintaining costly product displays by keeping inventory on pallets and limits distribution expenses by storing its inventory at point of sale in the warehouse. Given Costco’s frugal cost structure, the firm is able to price its merchandise below competing retailers, driving high sales volume per warehouse and allowing the retailer to generate strong profits on thin margins. Costco operates over 600 warehouses in the United States and boasts over 60% market share in the domestic warehouse club industry. Internationally, Costco operates another 270 warehouses, primarily in markets such as Canada, Mexico, Japan, and the UK.

Berkshire Hathaway is a holding company with a wide array of subsidiaries engaged in diverse activities. The firm's core business segment is insurance, run primarily through Geico, Berkshire Hathaway Reinsurance Group, and Berkshire Hathaway Primary Group. Berkshire has used the excess cash thrown off from these and its other operations over the years to acquire Burlington Northern Santa Fe (railroad), Berkshire Hathaway Energy (utilities and energy distributors), and the companies that make up its manufacturing, service, and retailing operations (which include five of Berkshire's largest noninsurance pretax earnings generators: Precision Castparts, Lubrizol, Clayton Homes, Marmon, and IMC/ISCAR). The conglomerate is unique in that it is run on a completely decentralized basis.
