What’s the Matter With Trumpland?

But what’s behind this divergence? What’s the matter with Trumpland?

Regional disparities aren’t a new phenomenon in America. Indeed, before World War II the world’s richest, most productive nation was also a nation with millions of dirt-poor farmers, many of whom didn’t even have electricity or indoor plumbing. But until the 1970s those disparities were rapidly narrowing.

Take, for example, the case of Mississippi, America’s poorest state. In the 1930s, per-capita income in Mississippi was only 30 percent as high as per-capita income in Massachusetts. By the late 1970s, however, that figure was almost 70 percent — and most people probably expected this process of convergence to continue.

But the process went into reverse instead: These days, Mississippi is back down to only about 55 percent of Massachusetts income. To put this in international perspective, Mississippi now is about as poor relative to the coastal states as Sicily is relative to northern Italy.

Mississippi isn’t an isolated case. As a new paper by Austin, Glaeser and Summers documents, regional convergence in per-capita incomes has stopped dead. And the relative economic decline of lagging regions has been accompanied by growing social problems: a rising share of prime-aged men not working, rising mortality, high levels of opioid consumption.

An aside: One implication of these developments is that William Julius Wilson was right. Wilson famously argued that the social ills of the nonwhite inner-city poor had their origin not in some mysterious flaws of African-American culture but in economic factors — specifically, the disappearance of good blue-collar jobs. Sure enough, when rural whites faced a similar loss of economic opportunity, they experienced a similar social unraveling.

So what is the matter with Trumpland?
