Walter Block on the pros and cons (from the government’s point of view) of income taxes and tariffs:
Every fiber of my economic being cries out against tariffs. If they are so good, why doesn’t each state in the US have one against the products of all of the other 49? That is, Ohio could “protect” its industries against the incursions from Arizona. This is obviously silly. One of the important reasons America is so prosperous is that we have a gigantic, internal, free trade area.
Donald Trump supports them on the ground that the McKinley administration was prosperous, and relied upon tariffs. But this is to commit the post hoc ergo propter hoc logical fallacy: that since A precedes B, A must be the cause of B. No, America did indeed become rich during this epoch, but that was in spite of tariffs, not due to their benign influence. If you are looking for a historical episode to shed light on this matter, the Smoot-Hawley Tariff of 1930 will do far better: it greatly worsened an already bad recession, plunging our economy into a deep depression.
Our President also claims that the US is victimized by a negative balance of trade: we buy more from Canada and other countries than they purchase from us. However, I have a horrid balance of trade with McDonald’s and Wal-Mart. I acquire several hundreds of dollars’ worth of their products every year, and neither has yet seen fit to reciprocate with any of my economic services (hint, hint!). On the other hand, I have a very strong positive balance of trade with my employer, Loyola University New Orleans. They pay me a decent salary; apart from a few lunches in their cafeteria, my expenditures to them fill their coffers to a zero degree. Should anyone worry about this sort of thing? Of course not. Ditto for international trade. If Country A buys more from B than it sells to it, money will flow from the former to the latter, reducing prices in the former and raising them in the latter, until matters balance out.
Everyone realizes the foolishness of tariffs when it comes to absolute advantage. No Canadian objects to the importation of bananas from Costa Rica. Producing this tropical product in the frozen North would be financially prohibitive (gigantic hothouses). Ditto for maple syrup in the country to the south. The only way they could produce this item would be to place maple trees in gigantic refrigerators. Ludicrous and prohibitively expensive.
But when it comes to comparative advantage, all too many people are out to lunch insofar as the teachings of Economics 101 are concerned. They fear that other countries might be more efficient than we are; with free trade, they would produce everything, we, nothing, and we would all starve to death from massive unemployment.
