There is so much we need to build right now. The housing crunch has spread across the country; by one estimate, we’re a few million units short. And we also need a huge build-out of renewable energy infrastructure — at a scale some experts compare to the construction of the Interstate highway system. And yet, we’re not seeing anything close to the level of building that we need — even in the blue states and cities where housing tends to be more expensive and where politicians and voters purport to care about climate change and affordable housing. Jerusalem Demsas is a staff writer at The Atlantic who obsesses over these questions as much as I do. In this conversation, she takes me through some of her reporting on local disputes that block or hinder projects, and what they say about the issues plaguing development in the country at large. We discuss how well-intentioned policies evolved into a Kafka-esque system of legal and bureaucratic hoops and delays; how clashes over development reveal a generational split in the environmental movement; and what it would take to cut decades of red tape.
