The new feudalism increasingly defines geography not only in America but across much of the world. The great bastion of both the Oligarchy and high reaches of the Clerisy lies in the great cities, notably New York, London, Paris, Beijing, Shanghai, Tokyo, San Francisco, Los Angeles and Seattle. These are all among the most expensive places to live in the world and play a dominant role in the global media.

Yet these cities are not the progressive, egalitarian places evoked by great urbanists like the late Jane Jacobs, but more closely resemble the “gated” cities of the Middle Ages, and their equivalents in places as diverse as China and Japan. American cities now have higher levels of inequality, notes one recent study, than Mexico. In fact, the largest gaps (between the bottom and top quintiles of median incomes are in the heartland of progressive opinion, such as in the metropolitan areas of San Francisco, New York, San Jose, and Los Angeles.

In some of the most favored blue cities, such as Seattle, Portland and San Francisco, not only is the middle class disappearing, but there has been something equivalent of “ethnic cleansing” amidst rising high levels of inequality, homelessness and social disorder. Long-standing minority communities like the Albina neighborhood in Portland are disappearing as 10,000 of the 38,000 residents have been pushed out of the historic African-American section. In San Francisco, the black population has dropped from 18% in the 1970s to single digits and what remains, notes Harry Alford, National Black Chamber of Commerce president, “are predominantly living under the poverty level and is being pushed out to extinction.”
