Skeptics might argue that the kind of scale that blitzscaling produces is inherently bad, and that society should simply prevent companies from growing too big. Testifying before Congress in 1911, future Supreme Court justice Louis Brandeis argued, “I think we are in a position, after the experience of the last twenty years, to state two things: In the first place, that a corporation may well be too large to be the most efficient instrument of production and of distribution, and, in the second place, whether it has exceeded the point of greatest economic efficiency or not, it may be too large to be tolerated among the people who desire to be free.”

We disagree with this position on the harmfulness of scale in today’s world. First, Brandeis was speaking during the era of “trusts,” when figures like J. P. Morgan consolidated American industry into powerful, giant companies like U.S. Steel. But we believe that today’s blitzscalers are qualitatively different than Gilded Age trusts. Those trusts held virtual monopolies over the supply of key physical resources like steel and oil. Consumers had no alternatives and were forced to do business with them. In contrast, companies like Apple and Amazon have to win their customers every day, and if they fail to do so, those consumers can simply buy Dell laptops and order books from Barnes & Noble.

Second, we believe that while big can sometimes be bad, big can also be great. Scale creates dominant companies, but scale also creates enormous value. The smartphones we love, for example, are mass-market consumer electronics that depend on economies of scale. While Brandeis is right that society needs to prevent monopolies that block technology or business innovation in the way that the old AT&T monopoly suppressed the progress of telecommunications, today’s largest companies have actually enabled innovation and the creation of even more value by providing a platform for everything from business productivity software (Slack) to entertainment (Netflix). Even the concentration of capital that scale has produced isn’t all bad; it has allowed blitzscalers to tackle “moonshots” like space travel (SpaceX) and autonomous vehicles (Google’s Waymo) that may dramatically improve our lives.
