"Senate Weighs Investing $120 Billion in Science to Counter China," trumpeted The New York Times in 2021. "A New Economic Patriotism Can Help Unite Our Divided Congress," argued Newsweek in 2023. "US cedes ground to China with 'self-inflicted wound' of USAid shutdown, analysts say," cautioned The Guardian in 2025. In recent years, we've been exposed to the latest version of a centuries-old geopolitical message: We all have a common enemy, and we all need to unite to fight it by making our own country stronger. That enemy—most commonly China—is threatening to outpace, if it isn't already outpacing, the US in infrastructural investment, educational programs, technological development, and elsewhere, and we need to devote millions, billions, even trillions of dollars to restoring the vitality of our institutions in order to reverse this trend. But why must defeating an "enemy" be the justification for policy that has the potential to benefit the public? Why should we just accept the premise that there must be an "enemy" to compete against and defeat? Why can't policy be enacted for the sole purpose of improving people's lives? And how does this messaging about the threat of a looming adversary serve the ruling class? On this episode, we detail the timeworn trope of the common enemy as a "unifying" device, looking at how increasingly so-called progressives are appealing to feel-good sentiments of unity and to the genuine needs for sound infrastructure, robust social safety nets, corporate regulation, and functional institutions in order to sell the idea that there is, and always will be, a shadowy bad guy that must be vanquished.
