Social regulation, on the other hand, promotes objectives that are not economic -- such as safer workplaces or a cleaner environment. Social regulations seek to discourage or prohibit harmful corporate behavior or to encourage behavior deemed socially desirable. The government controls smokestack emissions from factories, for instance, and it provides tax breaks to companies that offer their employees health and retirement benefits that meet certain standards. American history has seen the pendulum swing repeatedly between laissez-68

faire principles and demands for government regulation of both types. For the last 25 years, liberals and conservatives alike have sought to reduce or eliminate some categories of economic regulation, agreeing that the regulations wrongly protected companies from competition at the expense of consumers. Political leaders have had much sharper differences over social regulation, however. Liberals have been much more likely to favor government intervention that promotes a variety of non-economic objectives, while conservatives have been more likely to see it as an intrusion that makes businesses less competitive and less efficient.
