Johan Norberg, writing in the Wall Street Journal, explains that great civilizations depend on trade. Three slices:
If you want to understand what makes great civilizations possible, consider a walk on Monte Testaccio in central Rome. This 115-foot hill is actually an artificial mound, made up of fragments of millions of clay amphorae. These once held olive oil imported from Spain, North Africa and the Middle East and were discarded here after the oil was decanted at a nearby port.
Monte Testaccio, “the hill of broken pottery,” was built on international exchange. So was ancient Rome. The Greek orator Aristides claimed that to see all the products of the world, one had two choices: visit the entire world or simply go to Rome. “For whatever is grown and made among each people cannot fail to be here at all times and in abundance,” he wrote, “so that the city appears a kind of common emporium of the world.”
Visitors said almost exactly the same thing about other great civilizations of the past. A medieval observer described the Arab world during its golden age: “Everything produced from the earth is there. Carts carry countless goods to markets, where everything is available and cheap.” In Hangzhou, once the capital of Song China, Marco Polo observed markets linked by canals and warehouses that “supply them with every article that could be desired.”
Similarly, in the late 17th century, an English writer marveled at the Dutch Republic’s prosperity. Its land, he wrote, produced “neither grain, wine, oil, timber, metal, stone, wool, hemp, pitch, nor almost any other commodity of use; and yet we find there is hardly a nation in the world which enjoys all these things in greater affluence; and all this from commerce alone.”
Trade is not a byproduct of greatness but its foundation. Many civilizations have been centered on trade not because they had plenty of resources but because they didn’t.
……
Just as openness makes nations strong, isolation makes them fragile. The Four Horsemen of the Apocalypse are war, plague, famine—and trade barriers. The late Roman Empire undermined its commercial economy through centralization, regulation and debasing the currency. The late Abbasid caliphs militarized their economy in an effort to wrest control from the dominant merchants. After facing tariffs from other countries, the Dutch eventually implemented their own.
The sharpest anti-globalization reversal came in China after the Ming dynasty seized power in 1368, promising to restore stability at any cost. Foreign trade was made punishable by death, and soon even coastal trade was banned. The world’s greatest armada was allowed to rot in the harbor, and the Chinese court burned maps to prevent future voyages.
The result was stability indeed—and centuries of stagnation. China went from the world’s most advanced civilization to a poor one. By the 19th century, it was being attacked and humiliated by European powers that had become rulers of the seas.
…..
The lesson is clear: Protectionism might seem like a shield, but it easily becomes a cage. It’s a way of cutting a nation off from the world’s brains and skills, forfeiting not just wealth but the energy and constant renewal that make civilizations shine. Then all that remains are the fading memories of golden ages—and the broken shards of discarded amphorae.
I believe that I forgot to share this April 8th post, by Alex Tabarrok, on manufacturing and trade, so share it now. Here’s Alex’s conclusion:
Ensuring a robust manufacturing sector depends on sound domestic policies, innovation, and workforce development, rather than trying to devalue the currency or curtail trade. Far from being a nefarious cost, the U.S. role as issuer of the world’s reserve currency confers significant financial and economic advantages that, in the long run, do not meaningfully erode the nation’s manufacturing base.
Je suis honoré – I’m honored – and delighted that the Journal des Libertés translated and published my paper, originally titled “Championing Free Trade In an Era of Economic Nationalism: What Should Economists Do?”
GMU Econ alum Dominic Pino asks “what is wealth?”
Stanford University economic graduate student Jon Hartley reports on his noble resistance to Stanford’s toxic Graduate Workers Union. A slice:
I’m working as a teaching assistant while studying for a doctorate in economics at Stanford, but a campus union is trying to get me fired. The Stanford Graduate Workers Union wants my head on a plate because I refused to sign a membership form and pay dues. I won’t fund an organization whose values and tactics I don’t support.
Similar unions across the country are using their bargaining power not to improve working conditions but to coerce ideological conformity. This isn’t solidarity; it’s suppression. Shame on Stanford for going along with it.
Scott Lincicome decries the amount of time stolen from us Americans by our own government’s ludicrous regulations. A slice:
Before you ask, yes, the TSA shoe rule was needless. As Reason’s Jacob Sullum just detailed, the rule was implemented in 2006—five years after infamous (and clueless) “shoe bomber” Richard Reid first boarded an American Airlines international flight and then tried to ignite explosives in his sneakers (some urgency!). Even back then, the rule made little sense: A week before TSA adopted it, the agency was still advising people that shoe removal was unnecessary, and terrorism experts questioned whether a “shoe bomb” could actually avoid detection and take down a plane. “If you search people’s shoes,” security expert and TSA critic Bruce Schneier toldNewsweek last month, “they’ll just put the bomb somewhere else, like in another piece of clothing.”
The initial skepticism of the rule has only grown over time. In 2011, for example, aviation security experts doubted that the rule was necessary or effective in deterring terrorism, and then-Homeland Security Secretary Janet Napolitano promised the rule would be eliminated “in the months and years ahead.” Most damningly, almost no other places adopted the shoe rule—including common terror targets like Israel (which spends much more on airport security overall). Another clear indication of the rule’s pointlessness: It was nixed last month without any new shoe-safety technologies having been widely deployed.
As Massachusetts Institute of Technology security expert Yossi Sheffi admitted back in 2011, “this seems to be a make-everybody-feel-good thing rather than a necessity.” It’s thus a classic case of “security theater”: onerous and/or annoying government rules and procedures that are originally imposed to assuage public fear of criminal activity but do little or nothing to actually reduce it.
Yet it took 19 years for the government to reverse course.
My GMU colleague over in the Scalia School of Law Todd Zywicki writes insightfully about the separation of powers in the United States.
Arnold Kling reaches this sound conclusion:
When it comes to integrity, the decline from Eisenhower to Trump has been steep. Our system of government, with its checks and balances, is supposed to be robust with respect to the personal qualities of its leaders. But I am not sure that it is robust enough.
