Argentina is a reminder of one of the most forgotten caveats in history. Class struggle, Marx said, would either end "in a revolutionary reconstitution of society at large" or "in the common ruin of the contending classes." We might want to put a little more emphasis on that second part.
Argentina, though, hasn't just been hurt by people fighting over power. It's also been hurt by what people have done in power. Right-wing governments had no interest in educating the workers or investing in anything other than the landowners' exports. And left-wing governments just nationalized industries, protected others with tariffs, and made promises they could only afford by printing money. The result was a century of inflation and stagnation.
As The Economist points out, Argentina went from having an income per capita that was 92 per cent of 16 of the richest countries in 1914 to just 43 per cent today. The irony, of course, is that even when Argentina did open up its economy and try to cure its congenital inflation in the 1990s, the way it did so - pegging the peso to the dollar one-to-one - made it unable to respond to even the smallest shock. So when one came along, Argentina ended up in its own private Great Depression.
The point is that nothing is inevitable. The arc of the political universe is long, and it doesn't have to bend toward progress or justice or anything else good. It can point backwards if that's where we aim it. And we might.
Like Argentina, we have high levels of inequality. And also like Argentina, we have pretty extreme political polarisation. But what really might make us like Argentina is if we have politicians who deride expertise, who think that policy is something that fits into 140 characters, and who hint that elections are only something you have to respect if you win.
The United States, in other words, could still be Argentina.
