Protectionists favour tariffs and other trade barriers to reduce imports from abroad and to prevent businesses from buying labour in other countries through outsourced manufacturing or service jobs. However, most economists agree that the benefits of trade far outweigh the costs.
To be sure, there are disruptions from expanding trade as existing jobs may disappear — to be replaced by new ones requiring different skills. But cheaper products reduce prices to consumers. Most economists believe that the “consumer surplus” that results from lower prices far outweighs the cost of lost jobs or lower wages. Furthermore, trade stimulates productivity growth because it makes possible enormous economies of scale in manufacturing, services and marketing, and enhances competition. For example:
Workers are also dislocated by technological changes that may rapidly make existing products obsolete. Klein, a professor at Tufts University, says that portability of corporate benefits like pensions and health insurance would more directly address some costs of job dislocation.
