Leftist politics are fundamentally about dividing up spoils. Leftists see this as zero-sum: whatever you’re getting, I’m not getting. This is one reason why infrastructure is the very worst in the bluest, richest states. The left no longer holds to any conception of a common good. Hence in the areas they control, politics is all about who gets what, and public projects either don’t happen, take forever, and/or are ruthlessly exploited by rent-seekers.
