The debate over federal regulation has long been at the center of political contests. But surprisingly, the degree of agreement about regulation is considerable. No serious commentator denies that regulation is essential to ensuring well-functioning markets; protecting the health and safety of workers and families; and preventing fraud, corruption, and theft. Smart regulation is what makes cars safe to drive, lakes and rivers safe to swim in, and food safe to eat. At the same time, every serious commentator recognizes that poorly designed regulations can be detrimental; they can stack the deck in favor of special interests, prevent competition, and inhibit innovation.
