This is not Marxist by any means, but I have to use Marxism as an example. The problem with Marxism is that whenever it doesn't work, people say it wasn't tried enough. In the examples where it does work, there's always some special attribute or thing that causes it to, like a very small sample size. Yes it works in some cases and at some scale, but it never really works in a practical way. It's just a cluster of feelings about fairness in search of an practical application. This is, by definition, a "loose analogy". Finland has schools. So do we. Finland does all these things to make their schools better. So should we?
I love Finland, and I admire the Fins I've worked with. But I think we can play this game of "If we were only like Europe" only so much without actually having to apply some critical thinking skills. We are not like Europe -- as much as we'd like to be. I've been reading articles that claim we can improve various parts of society if we were only like some European country my entire life. If I didn't know better, I'd think a lot of academics spend time in Europe and become Europhiles the rest of their lives, much to the rest of our detriment. Seems like no matter how hard we try at these things, we can never be like European country X. There's probably a good reason for that. My best guess is that this has something to do with culture, but I'm not sure. If you want a country of Fins, perhaps you should consider moving to Finland?
So yes, maybe there's something here, but I have no idea what it is. Does the author suggest outlawing private schools? Perhaps indoctrinating our national culture with pithy slogans like "accountability is what's left when you take responsibility away"? Tighter control over immigration so the culture is more cohesive? Greater oil revenues? Decrease our population to 1/70th of its current size? More alcohol consumption? What is there that's here that we can take away and use today aside from a general admiration of how nice Finland is?
