SS: Amazing to me, About ten years ago I manually loaded similar data into XL from the 95 world almanac, however I used per-capita personal income and selected motor vehicle stats, and came up with similar results. I remember manipulating the data and generating about 25 different columns of data & charts. At the time I was still working full time. I blew it off to the fact that across the US the value of the dollar is not equal. For instance, while traveling I never eat or stop along my route, I always exit, and find some small town, and the last surviving mom & pop restaurant or motel. There is always a kind of gebmutliehite that is not present elsewhere, corporate businesses can not provide that type of friendliness, and when they do it always seems to be not sincere. You can not buy the contentment and life of these small town folks. You have to live it, and it will never be fitted into a gated community. The value of their life style is worth much more than the value of their paycheck or earnings. After running countless service jobs in the oilfield you learn much about small town life and their values. Perhaps being a farm-boy I still have their common values.
You DID mean say 'gemütlichkeit' (warm, friendly, cozy) don't you?

I fully agree with you about small, out of the way places. I used to do a good deal of business travel, and I always found it so depressing to be eating dinner at some mediocre franchised chain restaurant in a strip mall almost totally identical to any other strip mall in the country.

Just as a high degree of variation is essential for a healthy biosphere, so is a high degree of variation essential to a culture. Without it, we just become one big ant hill.

Joule: Thanks for the spelling, it was not in my German dictionary. I doubt there is an accurate English translation. I think it means the warm fuzzy you get after your second glass of wine, while having dinner with friends, and the fireplace is in full crackling flame in the dead of winter.  
BTW  what came first the joule or the watt-second?
