Abundance (Klein and Thompson book)

Abundance is a nonfiction book by Ezra Klein and Derek Thompson published by Avid Reader Press in March 2025. The book examines the reasons behind the lack of progress on ambitious projects in the United States, including those related to affordable housing, infrastructure, and climate change. It became a New York Times Bestseller.

Klein and Thompson argue that the regulatory environment in many liberal cities, while well intentioned, stymies development. They write that American liberals have been more concerned with blocking bad economic development than promoting good development since the 1970s. They say that Democrats have focused on the process rather than results and favored stasis over growth by backing zoning regulations, developing strict environmental laws, and tying expensive requirements to public infrastructure spending.

Klein and Thompson propose an Abundance Agenda that they say better manages the tradeoffs between regulations and social advancement and lament that America is stuck between a progressive movement that is too afraid of growth and a conservative movement that is allergic to government intervention. They present the abundance agenda both as a Third Way policy alternative and as a way to initiate new economic conditions that will diminish the appeal of the "socialist left" and the "populist-authoritarian right".

The book received a mixed reception from critics. Critics praised the scope and clarity of the ideas presented, while some viewed the book as pointing out problems without identifying realistic solutions.
