Ha-Joon Chang, economist at Cambridge University, is a familiar author to many in the general public by now for his persistent and eloquent efforts (when writing) to combat the economic orthodoxy on several major policy points. In particular, he is known for his defense of protectionism as a means to promote economic growth and for his rejection of the idea that 'free trade' and 'free markets' lead to better outcomes than alternatives such as government dirigisme. In "23 Things They Don't Tell You About Capitalism", he attempts to make the lessons of heterodoxy familiar to as wide a public as possible, addressing 23 orthodox economic clichés that are often accepted by a skeptical general public only because they seem to be supported by all in the economic field. In making the counterarguments accessible and generally known, Chang has done the English-speaking world a great service.
The 23 things he discusses can be roughly clustered into a number of groups: he discusses the orthodoxies of free trade as against protectionism, the orthodoxies of free markets as against government intervention, the orthodoxies of wage policy (particularly the idea that wages are infallibly determined by individual marginal productivity), the orthodoxy that inequality of income and outcome does not matter, and finally the idea that financial managers and economists know best. On all of these points, he has very important lessons to convey to policymakers, civil servants, and the general public to show that these things should either be rejected out of hand or be taken with a large truckload of salt. Using the strengths of economic history, he accessibly shows in each of these cases how the cliché is either refuted by the facts or itself an incoherent idea, or both.
That said, sometimes his critique does not go quite far enough, and this shows the limitations of Chang's own economic theory standpoint. As he makes clear, the book itself is intended to criticize the orthodoxies of 'free market' capitalism, but not capitalism itself. As a result, his critique is not as powerful and does not convey as many important popular lessons as it could. For example, although he is quite right about the relation between protectionism, government intervention, and growth, he does not criticize the concept of growth itself as the only goal in economic policy, nor does he point out the essential fact that growth can in fact be bad for the median living standard if it causes the distribution of wealth to be more unequal. He also, because of his market economy predilections, vastly understates the success of planned economies historically, despite referring at one point of the book to Robert Allen's excellent research on Soviet industrialization policy. He also does not point out that the strong capitalist investor state he favors itself historically has tended to impede the development of more egalitarian outcomes and tends to be repressive of unions and collective action. Finally, he does not critique any of the assumptions of microeconomics, only macroeconomics.
Nonetheless, most of the 23 lessons are well taken and although I have some disagreements with a number of them, they are exceedingly well formulated for public understanding and indeed much closer to a real picture of how capitalist economies work than any of your average macroecon textbooks. It is therefore to be hoped that this book will have a wide audience.
