Yes, if ever there was class warfare it's here. Interesting to note the difference between Ann Arbor and Detroit. They're both equally leftist in the last two generations, but one (Detroit) is a by-product of the other's thinking ala (Ann Arbor).
I'm in much more conservative Jackson county which is kind of an oddball county. We used to be a manufacturing powerhouse with Goodyear, Yardman, Clark Equipment etc. Now our manufacturing base has almost entirely collapsed leaving welfare and low paying retail jobs but we still seem to hold the conservative values.
