Samuel Hammond uses a National Review Online column to critique U.S. Sen. Elizabeth Warren’s latest proposal targeting American corporations.

The ability of businesses to grow rapidly is a one of the most defining and precious features of the American economy. Amazon went from a fledgling online bookstore to an “everything store” and the second-largest employer in the United States in just two decades. Uber emerged from nowhere less than ten years ago to become a dominant transportation option in cities around the world. And earlier this month, Apple became the first U.S. public corporation to reach a $1 trillion valuation — a far cry from its sorry state in 1996, when it looked doomed to fail.

It’s not just the information sector. The United States is home to 64 percent of the world’s billion-dollar privately held companies and a plurality of the world’s billion-dollar startups. Known in the industry as “unicorns,” they cover industries ranging from aerospace to biotechnology, and they are the reason America remains the engine of innovation for the entire world.

Unless Elizabeth Warren gets her way. In a bill unveiled this week, the Massachusetts senator has put forward a proposal that threatens to force America’s unicorns into a corral and domesticate the American economy indefinitely.

Dubbed the “Accountable Capitalism Act,” Warren foresees the creation of an Office of United States Corporations that would require any company with revenue over $1 billion to obtain a federal charter, binding company directors to “consider the interests of all corporate stakeholders — including employees, customers, shareholders, and the communities in which the company operates.”
