A wave of consolidation has given a few large companies control of proprietary, multi-level systems of traits, seeds, agrochemicals and digital technology.

Amid Congressional investigation and federal, state and private antitrust cases, all eyes are on Big Tech. The step up in antitrust enforcement against the digital technology behemoths and their alleged abuses of market power is, by all accounts, good news. Successful cases could restore competition, which would benefit smaller businesses and American consumers alike. And after decades of under-enforcement of the antitrust laws in the United States, these cases could deliver some base hits—and even home runs—for a critical area of law enforcement.

But the outsized media, political and social attention paid to the tech industry has diverted focus from other important sectors. There are monopolies and domestic cartels elsewhere—in healthcare, pharmaceuticals, media and communications, as well as food and agriculture. These industries produce goods and services that are essential to the health, safety and well-being of consumers, and even to our national security, which is why antitrust laws must be enforced against violations in these sectors, too.
