There's no question in my mind that North America has gotten a lot worse at completing great civic projects.Sometimes, that's for good reasons. We don't have slave labor, we have environmental review, and we allow affected communities to protest and block approval. In the old days when the city fathers had a bright idea they'd just plow through the neighborhood of $LEAST_POWERFUL_ETHNIC_GROUP.We might have overcorrected! But I also don't know what model there might exist for moving quickly with a multi-stakeholder process.
