As to why Europe is different, I would argue that it is a function of history. They are simply older nations that have cities from hundreds of years ago, thus they are still compact and don't require cars. Notice that our older cities (NY, Boston) are more like Europe. But our younger cities are more auto-centric.

As for our political leadership. I am rather cynical on this topic. I look at our last Presidential vote. Both Bush and Kerry were members of Yales Skull and Bones. My point being is that it is all beyond our control. We really have no say in who runs, wins, or the decisions they make afterwards. Just my opinion.

Hell, I don't have AC in my place. "But, you live in Alaska where it's cold" you say...yes it is cold in winter...like -50F in Jan. BUT our highs in the interior get into the 80s regularly and we have a week or two of 90s every year.
