A tariff is a tax levied on a foreign good, to help a special interest at the expense of American consumers.
A trade restraint or marketing agreement—on the number of inexpensive Taiwanese sneakers that Americans can buy, for example—achieves the same goal, at the same cost, in a less forthright manner.
And all the trends are towards more subsidies for U.S. exporters, and more prohibitions and taxes on imports.
Trade is to be subsidized or restrained, not left to the voluntary actions of consumers and producers.
In 1930, Congress passed the Smoot-Hawley tariff bill, imposing heavy tariffs on imports, with the avowed motive of “protecting” U.S. companies and jobs. Within one year, our 25 major trading partners had retaliated with their own tariffs on American goods. World trade declined sharply, and the depression was made world-wide and longer-lasting.
Today the policy of protectionism is again gaining favor in Congress, and in other countries. But it must be fought with all our strength.
Not only does protectionism make everyone poorer—except certain special interests—but it also increases international tensions, and can lead to war.
“If a foreign country can supply us with a commodity cheaper than we ourselves can make it,” wrote Adam Smith in 1776, “better buy it of them with some part of the produce of our own industry, employed in a way in which we have some advantage. The general industry of the country will not therefore be diminished... but only left to find out the way in which it can be employed to the greater advantage.”
An important economic principle is called the division of labor. It states that economic efficiency, and therefore growth, is enhanced by everyone doing what he does best.
If I had to grow my own food, make my own clothes, build my own house, and teach my own children, our family’s living standard would plummet to a subsistence, or below-subsistence, level.
But if I practice medicine, and allow others with more talent as farmers, builders or tailors to do what they do best, we are all better oft: Precious capital and labor are directed to the areas of most productivity, and through voluntary trading, we all benefit.
This principle works just as effectively on a national and world-wide scale, as Adam Smith pointed out.
All of you Free Traitors™ will never admit that consumption taxes, like the tariff, are superior to the income tax. Why? To admit that ruins your religion.
So forget trade, tariffs can be justified on the revenue generation aspect alone. Tariffs are not mandatory, the income tax you free trade Nazis tacitly support certainly is mandatory with incarceration the ultimate threat. Nobody ever got thrown into jail for not buying an imported good.
