Right, I think the real bill would be far more than double, but I haven't looked into this topic in depth, so I can't really say. While the party lasts, and the suburbs are heavily subsidized by cities/debt markets, sure, you'd have a hard time convincing the people being subsidized to change their ways. If that party ends, I think economic reality will do all the convincing. But markets and policy can stay irrational for a very long time, so who knows.
