This book is pretty blatantly biased in the free market direction, and it colors everything in the book, but I'm going to go with 4 stars, and here's why:
About every other summer, I think something like, "You know, there's no excuse for a mathematician to be so woefully ignorant of economics; I should do something about it." I then pick up an economics book, make a valiant attempt to read it, get wildly pissed off at the overuse of jargon, muddled thinking, confusion of causation and correlation, and general methodologies, and then I throw the book out the window.
Now part of this is entirely cultural. Mathematicians are primarily logicians, which means we start with a set of assumptions then follow them to a logical conclusion. If our conclusions fit with the world, then we're very happy, and if not, then we're not as happy, but we're still pretty happy. If we really want to model the world, we will change our assumptions. But regardless, we learned something: this set of assumptions yields this conclusion. In many ways, this is the opposite of science, which is primarily concerned with the world-as-it-is, and hence you want any assumptions to be the right ones to model the world. I think this (limiting) aspect of science annoys some mathematicians, and this (unreal) aspect of mathematics annoys some scientists.
Regardless, the methodology of economics has always seemed something like this, to me: start with some assumption about how you think something works (for example, it could be something fairly innocuous, like "higher prices decrease demand," or it could be something much more dangerous, like "the government does a really good job at running things"), then you interpret all the real-world data under the assumption that your original hypothesis was true. It's pretty clear why this is dangerous: if your original assumption is wrong, then all your following conclusions are at best tainted, and at worst totally false. And this methodology doesn't give you very good opportunities to re-assess your hypotheses. (Again, in math, you don't have to model any specific physical system, like you're supposed to in economics, and in science, the goal is to proceed with some limited--and revisable--set of assumptions.)
Anyway, I don't think this is necessary a valid opinion of what economics "is." (In fact, it might not even be a valid opinion of what science is. Or even what math is.) But it's certainly the impression I've always gotten, and I haven't particularly changed it yet.
But this book finally explained some things to me! Sowell starts with an excellent definition of his subject (something I don't think I've read before): Economics is the study of how people deal with scarce resources. And that makes sense to me: it's not about money, or financial institutions, or politics: it's just about corn. There's only x amount of corn, and people want y amount of corn, so how do we apportion it? See, that wasn't so hard.
So, when it boils right down to it, I learned an incredible amount from this book. I learned that economics is about scarcity. I learned about unintended consequences (a common talking point for many academics, and something pretty ignored by politicians.) And, while I have never considered myself a capitalist, I have to say that Sowell makes some excellent points and has left me wavering somewhat. (Of course, my real problem isn't with capitalism, it's with consumerism ; but how do we separate these?) Anyway, it had a huge impact both on my positions and opinions, but also on my outlook and how I think about things.
Let me reiterate, before I complain, that I'm now standing WAAAAY closer to Sowell's position that I was before reading the book. In the list of "Books That Strongly Affected My Opinions," this one is in the top 10 easy. But...
I do find his brutal insistence in the amorality of all of this to be disturbing. I completely understand his points, but I just don't necessarily want to live in his world. He seems to conclude, "The free market will do the best for the most people." (How utilitarian!) But I'm forced to say, "Can't we do better?" It could be my religious convictions, or my natural kindness (yeah, right), but I still feel compelled to help the helpless. And his insistence that I shouldn't seems pretty terrible.
And it all seems so rife for abuse. Many of his arguments revolve around the implicit assumption that the consumers are well-informed, but this isn't necessarily true. There are still an awfully lot of products being sold in stores in America made by, at best, "essentially slavery," and at worst "blatant slavery." But we don't necessarily know that, so our dollars don't necessarily reflect what we actually think. But who has time to research every product and study all that? The economy is just too big! (Yes, I know I'm idealistic: I'm still laboring under the possibly-mistaken assumption that people really wouldn't buy something that was a little cheaper if they knew it was made by actual human slaves.) In general, Sowell's blatant faith in the free market system seems as Utopian as the communism he *repeatedly* denigrates. (And by "repeatedly," I mean "r.e.p.e.a.t.e.d.l.y.")
And there's the real problem with many of his opinions in this book. Despite his faith (I don't know what else to call it) that the free market will fix everything, it's just not clear how the free market prevents the kind of slavery common in America 200 years ago, or children working in factories 300 years ago, or the general income inequality that's becoming so rampant in this country right now. And his insistence that "greed" just isn't really a thing that affects anything is patently ridiculous--I certainly must have misunderstood his point. You might as well say that lying or f@#%ing wasn't a real thing.
There are some other problems of varying levels: I did find some numbers in the book that weren't valid, but not many, and they didn't seem to affect his argument. He (seems to) repeatedly confuse causation and correlation, but with something as complicated as an economy, is there any way to measure causation? (Is this a question for Economics as a whole?) Also, he seems to think that America has the highest standard of living in the world, and I'm pretty sure this is false on most scales, but he never says what scale he's using, so maybe that's OK. (But it did seem a little bit like the silly sort of nationalism you see on TV. "Of course America has the highest standard of living: it's America, after all.")
But, having complained about his blatant bias, I do applaud how BLATANT it is. He doesn't hide it, or try to sneak it in: he's up front about it, it colors everything, so you know exactly where he stands. He's proselytizing, but he's doing it honestly. (Like the door-to-door evangelists who open up with, "Hey, I'm from The Church...") And I appreciate that.
So, in summary: learned a lot. Enjoyed the read. Very biased, but very up-front about it. Morally problematic.
