Complex Systems with Patrick McKenzie (patio11)3 Heinä 2025

Achieving results in the physical world, with Adam Jarvis of “Public Service”

Patrick McKenzie is joined by Adam Jarvis, author of the Public Service substack and a New Zealand civil engineer and public sector veteran. They discuss how political capital constraints, funding misalignment across government levels, and accumulated regulatory "scar tissue" make infrastructure projects extraordinarily difficult. The conversation reveals why replacing a water pipe now costs more in planning than the entire project did a decade ago, and how talent sorting has drained capacity from public institutions. Despite these challenges, Patrick and Adam find reasons for optimism about reforming government capacity.
