Ezra Klein and Derek Thompson's Abundance was one of the most talked about policy books of 2025. In broad strokes, the book makes the case for "a liberalism that builds" and thus becomes the basis for a more affordable and more sustainable--or, they would say, abundant--future.

Much of the book provides a useful diagnosis of how existing policies and regulations make it too difficult to build hosing, deploy clean energy, develop innovative technologies, and bring innovations to market. In this respect, it is a useful intervention in policy debates that challenges the contemporary approach to governance to which many of their ideological compatriots are committed. Yet, as I note in my review in Regulation, the book has its blind spots.
