This is a downright weird review. The crux of the complaint against Klein's book is that it's about values and avoids specific policy prescriptions. The lack of those policy arguments leads the reviewer to question Klein's commitment. But there's nobody in all of American political discourse that complaint falls more flat on than Ezra Klein.

The review draws a comparison between Abundance and Marc Andreesen's "Time To Build" essay, for... no discernible reason. It then points out that pmarca was ultimately hypocritical about building (he opposed development in his own town, of Atherton). I don't understand what that has to do with anything. Klein is a YIMBY. So am I. I spent my spare time working to clear the way for multifamily housing to get built right next door to my own. What the fuck do I care what pmarca did?

I think that, to understand this review, you have to understand the internal dynamics of the Democratic coalition. Progressives (the left of the party) hate Klein, and, for reasons passing understanding, the YIMBY movement writ large. The progressives have a prescription for rehabilitating the national coalition: massive public spending programs and single-payer health care. Klein and Thompson advocate for a different strategy: building a track record of demonstrated competence, and stanching/reversing the outflow of residents from blue states to red states that actually build housing. That there might be a strategy that doesn't involve a progressive takeover of the state and national parties is a problem for the movement; hence: stuff like this.

You'll see the same thing happening with Matt Breunig and Malcolm Harris' reviews, posted upthread.
