THE CASE FOR 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.
The argument in favor of tariffs that has the greatest emotional appeal to the public at large is the alleged need to protect the high standard of living of American workers from the "unfair" competition of workers in Japan or Korea or Hong Kong who are willing to work for a much lower wage. What is wrong with this argument? Don't we want to protect the high standard of living of our people?
The fallacy in this argument is the loose use of the terms "high" wage and "low" wage. What do high and low wages mean? American workers are paid in dollars; Japanese workers are paid in yen. How do we compare wages in dollars with wages in yen? How many yen equal a dollar? What determines the exchange rate?
Consider an extreme case. Suppose that, to begin with, 360 yen equal a dollar. At this exchange rate, the actual rate of exchange for many years, suppose that the Japanese can produce and sell everything for fewer dollars than we can in the United States--TV sets, automobiles, steel, and even soybeans, wheat, milk, and ice cream. If we had free international trade, we would try to buy all our goods from Japan. This would seem to be the extreme horror story of the kind depicted by the defenders of tariffs--we would be flooded with Japanese goods and could sell them nothing.
Before throwing up your hands in horror, carry the analysis one step further. How would we pay the Japanese? We would offer them dollar bills. What would they do with the dollar bills? We have assumed that at 360 yen to the dollar everything is cheaper in Japan, so there is nothing in the U.S. market that they would want to buy. If the Japanese exporters were willing to burn or bury the dollar bills, that would be wonderful for us. We would get all kinds of goods for green pieces of paper that we can produce in great abundance and very cheaply. We would have the most marvelous export industry conceivable.
Of course, the Japanese would not in fact sell us useful goods in order to get useless pieces of paper to bury or burn. Like us, they want to get something real in return for their work. If all goods were cheaper in Japan than in the United States at 360 yen to the dollar, the exporters would try to get rid of their dollars, would try to sell them for 360 yen to the dollar in order to buy the cheaper Japanese goods. But who would be willing to buy the dollars? What is true for the Japanese exporter is true for everyone in Japan. No one will be willing to give 360 yen in exchange for one dollar if 360 yen will buy more of everything in Japan than one dollar will buy in the United States. The exporters, on discovering that no one will buy their dollars at 360 yen, will offer to take fewer yen for a dollar. The price of the dollar in terms of the yen will go down--to 300 yen for a dollar or 250 yen or 200 yen. Put the other way around, it will take more and more dollars to buy a given number of Japanese yen. Japanese goods are priced in yen, so their price in dollars will go up. Conversely, U.S. goods are priced in dollars, so the more dollars the Japanese get for a given number of yen, the cheaper U.S. goods become to the Japanese in terms of yen.
The price of the dollar in terms of yen would fall, until, on the average, the dollar value of goods that the Japanese buy from the United States roughly equaled the dollar value of goods that the United States buys from Japan. At that price everybody who wanted to buy yen for dollars would find someone who was willing to sell him yen for dollars.
