In a recent column published in RealClearMarkets, Market Institute President Charles Sauer explains how Walmart’s rise to a trillion-dollar company illustrates the power of free markets—and why policymakers should rethink modern antitrust enforcement.
Walmart recently became only the second non-technology company to surpass a $1 trillion market capitalization, joining Warren Buffett’s Berkshire Hathaway. But as Sauer notes, Walmart’s success did not come from monopoly power. It came from relentless innovation and a commitment to lower prices for consumers.
As Sauer writes:
“Walmart’s success stems from Sam Walton’s decision to keep prices low at the expense of (temporarily) reduced profit margins.”
From its first store in Bentonville, Arkansas in 1962, Walmart expanded across the country and eventually around the world. Today the company operates more than 10,800 stores across 29 countries and employs over 2.1 million workers, making it the largest private-sector employer in the United States.
Yet Walmart’s growth has often been criticized by those who claim the company harms small businesses or American manufacturing. Sauer argues these critiques overlook a fundamental reality of market economies: consumers ultimately decide which businesses succeed.
As Sauer explains:
“What these critics ignore is that no one is forced to shop at Walmart. Consumers choose to do so because they benefit from the low prices and convenience.”
Lower prices mean that families can stretch their budgets further and spend their savings on other priorities—from housing to education to retirement.
Today, many of the same criticisms once directed at Walmart are now being aimed at Amazon. But Sauer notes that the two companies actually demonstrate the opposite of monopoly power. Instead of exploiting consumers, they must continually innovate to remain competitive.
Walmart has successfully adapted to the digital era by integrating its physical retail network with online shopping. The company is now the second most popular e-commerce site in the United States and one of the most visited websites in the world.
As Sauer writes:
“If Walmart and Amazon were true monopolies, they would not continue to innovate or keep prices low. Instead, they would use their monopoly power to raise prices and not spend valuable capital developing new services.”
The continued competition between large firms—and the constant threat of new entrants—forces companies to keep improving their products and services.
That reality has important implications for antitrust policy.
Rather than targeting successful companies simply because they are large, Sauer argues that policymakers should focus on removing the regulatory barriers that prevent new competitors from entering markets.
“Instead of demonstrating the need for government to aggressively enforce antitrust laws to break up large firms—Amazon and Walmart demonstrate how, in a free market, leading companies must continue to innovate and stay abreast of changing consumer tastes.”
In other words, the real threat to competition is rarely the success of large companies. More often, it is government policies that make it harder for new businesses to compete.
