In this and previous threads, people keep referring to Chile's economy as "neo-liberal" which is a term I'm unfamiliar with. I've always heard similar economic policy called "classical liberal" or simply free market capitalism.
In any event, I wouldn't call it a miracle, simply because Chile's strong and relatively stable economy is exactly what one should expect for a country that embraces the free market.
Of course, it's very hard to speak in absolutes, since Chile is hardly a perfect right-wing economic model. Just like Argentina is certainly not a true left-wing model. It's all really a matter of degree.
In any event, Santiago and Chile should be very proud of how they got rid of a corrupt regime, and replaced it with a democrasy, all without falling victim to far-left demagouges like some of their unfortunate neighbors to the North.
