An excellent synopsis, missing the mark only slightly by failing to directly confront the "800 pound gorilla" in the living room, which is that it is not totally liberalism, but "african-American" liberalism that has killed Detroit.
Detroit is a worst-case scenario, but a similar fate has befallen all US cities with a majority black population, and an "african-American" political administration. "White flight" exists for a reason, and one can cry "racism" all they want, but the fact remains that not only whites, but working and middle class minorities of all stripes will flee from these urban areas when anarchy is allowed to thrive, and valuable resources are channeled into welfare and "black culture" projects at the expense of vital services. The anarchy is further compounded by "politically correct" police practices that tolerate, rather than deter criminal activity.
Detroit made its own bed......let them lay in it........
