From a 1997 interview with Milton and Rose Friedman on the importance of free trade:
One voice that is hardly ever raised is the consumer's. That voice is drowned out in the cacophony of the "interested sophistry of merchants and manufacturers" and their employees. The result is a serious distortion of the issue. For example, the supporters of tariffs treat it as self evident that the creation of jobs is a desirable end, in and of itself, regardless of what the persons employed do. That is clearly wrong. If all we want are jobs, we can create any number--for example, have people dig holes and then fill them up again or perform other useless tasks. Work is sometimes its own reward. Mostly, however, it is the price we pay to get the things we want. Our real objective is not just jobs but productive jobs--jobs that will mean more goods and services to consume.
Another fallacy seldom contradicted is that exports are good, imports bad. The truth is very different. We cannot eat, wear, or enjoy the goods we send abroad. We eat bananas from Central America, wear Italian shoes, drive German automobiles, and enjoy programs we see on our Japanese TV sets. Our gain from foreign trade is what we import. Exports are the price we pay to get imports. As Adam Smith saw so clearly, the citizens of a nation benefit from getting as large a volume of imports as possible in return for its exports or, equivalently, from exporting as little as possible to pay for its imports.
The misleading terminology we use reflects these erroneous ideas. "Protection" really means exploiting the consumer. A "favorable balance of trade" really means exporting more than we import, sending abroad goods of greater total value than the goods we get from abroad. In your private household, you would surely prefer to pay less for more rather than the other way around, yet that would be termed an "unfavorable balance of payments" in foreign trade.
