So has anyone read it? I hope so, and I hope more do. Joseph Heath is a philosophy prof at U of Toronto, and he self-identifies as a leftish type whose initial experiences with economics turned him off.
But he came back to the subject, and he managed to figure out many important things without using the mathematical tools that economists teach each other. This means that it's much more accessible to non-economists, and it still makes sense.
It's a great book, and I don't say so just because he deals with many of the themes I've dealt with here. There's an interview with him at The Walrus:
I think over the course of the twentieth century, the Left has had a huge amount of success in terms of identifying the problems with capitalism, and kind of sounding the alarm. In other words, the kinds of issues that people have raised on the Left, along with the view that markets will not automatically fix them, have been pretty dead on, everything from race relations to environmental problems to wages... [T]he Left is extremely good at diagnosing flaws in the system, it's just that because of, often, a lack of sophistication in economic reasoning, people have invented totally crazy stories about what's actually generating these defects. And as a result, the policy prescriptions that come out of the Left are often just terrible.
