William Graham Sumner on free trade as another aspect of individual liberty (1888)

William Graham Sumner was not only a founder of American sociology but an ardent free trader. He wrote an important history of tariffs in America as well as popular works on free trade for newspapers. In his book Protectionism: the -ism which teaches that waste makes wealth (1888) was written at a time when free trade was under attack, when it was rejected by “practical”men of business and politics who dismissed it as “mere theory.” Interestingly, Bastiat was met with the same criticism by protectionists 40 years earlier (see his article “Theory and Practice” (c. 1845).

In this passage Sumner makes two important points. Firstly, that critics of free trade already live in a large country which has complete freedom of trade within its borders, hence he accuses them of hypocrisy for not arguing for tariff barriers between the states. Secondly, for not appreciating the fact that the free trade movement is like other historical movements for individual liberty such as for freedom of expression, freedom of religion, and the abolition of slavery. If free trade was only “mere theory”, then so were all these other movements which have greatly improved the lives of human beings.
