It is true that policymaking requires expertise. But I don’t think members of the public are demonstrating ignorance when they claim that drug prices are too high, taxes could be fairer, privacy laws are too weak and monopolies are too coddled.

Others remind us that the United States is a democratic republic, not a direct democracy, and that the Constitution was designed to modulate the extremes of majority rule. Majorities sometimes want things — like bans on books, or crackdowns on minorities — that they should not be given.

This is true. It is also true that a thoughtful process of democratic deliberation and compromise can yield better policy outcomes than merely following the majority’s will. But these considerations hardly describe our current situation. The invocation of constitutional principle has become an increasingly lame and embarrassing excuse. The framers of the Constitution, having experienced a popular revolution, were hardly recommending that the will of the majority be ignored. The Constitution sought to fine-tune majoritarian democracy, not to silence it.

The most obvious historical precedent for our times is the Progressive era. During the first decades of the 20th century, the American public voted for politicians who supported economic reforms like maximum-hour work laws and bans on child labor. But the Supreme Court struck down most of Congress’s economic legislation, deeming it unconstitutional.

In our era, it is primarily Congress that prevents popular laws from being passed or getting serious consideration. (Holding an occasional hearing does not count as “doing something.”) Entire categories of public policy options are effectively off-limits because of the combined influence of industry groups and donor interests. There is no principled defense of this state of affairs — and indeed, no one attempts to offer such a justification. Instead, legislative stagnation is cynically defended by those who benefit from it with an unconvincing invocation of the rigors of our system of checks and balances.
