Decades of both economic learning and efforts to restore a constitutionalist judiciary are at stake in the current antitrust debate. While there are plenty of problems with Big Tech, attempting to turn antitrust law into a jack-of-all trades is a bad idea that risks improper application of the law and undercuts future cases of legitimate enforcement. Instead, advocates of antitrust reform need to identify both the specific problems they seek to fix and the appropriate body of law from which to draw a legal remedy. In many cases, the answer will not be antitrust.
