Yes, President Ronald Reagan made "deregulation" a cornerstone of his economic policy, known as Reaganomics, during the 1980s. While the movement toward deregulation actually began under the Ford and Carter administrations (particularly with the Airline Deregulation Act of 1978), Reagan significantly accelerated the process and expanded its scope. He focused on reducing the federal government's oversight of private industry to stimulate economic growth, cutting the budgets and staffing of regulatory agencies like the EPA and OSHA. He famously deregulated the financial sector, which included easing rules on Savings and Loan associations—a move that critics argue contributed to the subsequent S&L crisis. He also took a "hands-off" approach to antitrust enforcement, leading to a wave of corporate mergers. Reagan’s philosophy was built on the belief that government regulations were "red tape" that stifled innovation and productivity, and his administration's actions fundamentally shifted the American economic landscape toward a more free-market, "laissez-faire" approach that persisted for decades.
