Something that puzzles me is that any time progressive policies are being pushed through in not-USA, & someone references it in a USA policy discussion, there's a blanket "That wouldn't work here, we have 300 million people.." even in conversations where the policy should benefit from economies of scale (pharma). The main defense should be that there's a lot of unpopulated land which requires maintenance (highways). Of course, this issue applies to Canada as well, which is able to support more progressive policies
