In a Pittsburgh speech yesterday, Donald Trump illustrated what I call “nostalgia economics.” Trump, according to Politico, “vowed to bring back Pittsburgh’s once-thriving steel and coal industries at a rally here on Wednesday night.” Just as he has vowed to reverse decades of globalization and automation to “bring back” manufacturing jobs from Asia. But, as Politico’s Ben Shreckinger points out, Trump’s depiction of Pittsburgh might be outdated:

And his economic message may feel a bit anachronistic in a city that prides itself on its decades-long recovery from the collapse of the steel industry, which is no longer the major employer here. Pittsburgh’s dynamic mayor, William Peduto — a new-school Democrat who held a rally with Hillary Clinton here last week — has sought to make the city a laboratory for urban reinvention by luring tech companies and boosting its university-powered research sector. After years of decline, the economy has begun adding jobs again, albeit slowly, and unemployment rate is just under the national average.
