There is also a thing I noticed reading HN comments, when country pr city X does something good some US persons would jump immediately to find the reason this is absolutely impossible to be done in their local city,state or country. The "impossible" part is also most of the time defended with the excuse that US is bigger, less dense and freedom people have. I imagine though that in such a large country there must be some city somewhere with good infrastructure, with good housing and with low crime .... anyway I think people need to think more on "how can we achieve X" not "how can I prove that X is impossible so we do not need to try "
