I suspect that students from Wake Technical Community College are more proficient in economics

than Ivy League graduates (via Don Boudreaux):
Why is one-sixth of the world—the “first world”—different from the rest of the world? What did these countries do right that the rest of the world is not doing? This question is the focus of Adam’s Smith’s Wealth of Nations. I want to give my students the building blocks to answer this question. So, a year after I began teaching here, I tossed out the heavy principles text that I was given, adopted a small one, and narrowed the focus of my course.

In several principles-of-economics textbooks, the first chapter is devoted to the basic elements of economics such as scarcity, tradeoffs, opportunity costs, incentives, marginal thinking, etc. Most instructors spend very little time with this chapter.

I spend weeks on these concepts. These principles are at the heart of economics, which is, essentially, the study of human behavior. Economics explains how people make decisions—important ones such as where to go to college and unimportant ones such as which shampoo to buy.

Economics teaches us that if given a certain set of conditions and incentives, rational humans behave quite predictably. We need to look no further than the macroeconomic crisis that our nation is currently experiencing. As well-meaning government officials promoted homeownership over the years, the incentives they put into place led, gradually but almost inevitably, to a housing boom and then a bust. Those incentives included lower mortgage standards, the Federal Reserve’s low interest rate policy in 2002-2004, and changes in accounting rules that allowed financial institutions to expand their capital when asset prices rose but reduced their capital when asset prices fell.

Just as my students learn to understand the causes of today’s problems, they learn why conventional wisdom is often wrong. For example, most people think that rent control—government limits on rent increases—make the poor better off by keeping housing affordable. But my students understand the unintended side effects. In cities like New York, rich insiders are often the ones who get the breaks. Because landlords can’t get a market rent, few people want to build more apartments, so existing houses often cost more. When rents are low, landlords don’t want to make necessary repairs and in extreme cases they abandon the apartments.
What do the first-world nations have in common? Quite a bit: the rule of law, competitive markets, tax rates that are not excessive, efficient capital markets, etc. In short, the successful countries tend to have the most economic freedom.
