Protectionism - Arguments Against Protectionism

Arguments Against Protectionism

Protectionism is frequently criticized by mainstream economists as harming the people it is meant to help. Most mainstream economists instead support free trade. Economic theory, under the principle of comparative advantage, shows that the gains from free trade outweigh any losses as free trade creates more jobs than it destroys because it allows countries to specialize in the production of goods and services in which they have a comparative advantage. Protectionism results in deadweight loss; this loss to overall welfare gives no-one any benefit, unlike in a free market, where there is no such total loss. According to economist Stephen P. Magee, the benefits of free trade outweigh the losses by as much as 100 to 1.

Most economists, including Nobel prize winners Milton Friedman and Paul Krugman, believe that free trade helps workers in developing countries, even though they are not subject to the stringent health and labour standards of developed countries. This is because "the growth of manufacturing — and of the myriad other jobs that the new export sector creates — has a ripple effect throughout the economy" that creates competition among producers, lifting wages and living conditions. Economists have suggested that those who support protectionism ostensibly to further the interests of workers in least developed countries are in fact being disingenuous, seeking only to protect jobs in developed countries. Additionally, workers in the least developed countries only accept jobs if they are the best on offer, as all mutually consensual exchanges must be of benefit to both sides, or else they wouldn't be entered into freely. That they accept low-paying jobs from companies in developed countries shows that their other employment prospects are worse. A letter reprinted in the May 2010 edition of Econ Journal Watch identifies a similar sentiment against protectionism from sixteen British economists at the beginning of the 20th century.

Alan Greenspan, former chair of the American Federal Reserve, has criticized protectionist proposals as leading "to an atrophy of our competitive ability. ... If the protectionist route is followed, newer, more efficient industries will have less scope to expand, and overall output and economic welfare will suffer."

Protectionism has also been accused of being one of the major causes of war. Proponents of this theory point to the constant warfare in the 17th and 18th centuries among European countries whose governments were predominantly mercantilist and protectionist, the American Revolution, which came about ostensibly due to British tariffs and taxes, as well as the protective policies preceding both World War I and World War II. According to a slogan of Frédéric Bastiat (1801-1850), "When goods cannot cross borders, armies will."

Free trade promotes equal access to domestic resources (human, natural, capital, etc.) for domestic participants and foreign participants alike. Some thinkers extend that under free trade, citizens of participating countries deserve equal access to resources and social welfare (labor laws, education, etc.). Visa entrance policies tend to discourage free reallocation between many countries, and encourage it with others. High freedom and mobility has been shown to lead to far greater development than aid programs in many cases, for example eastern European countries in the European Union. In other words visa entrance requirements are a form of local protectionism.
