...in the American Conservative -- of all places -- that the rich are seceding from the U.S. It's a truly disturbing piece (my emphasis): 

I do not mean secession by physical withdrawal from the territory of the state, although that happens from time to time—for example, Erik Prince, who was born into a fortune, is related to the even bigger Amway fortune, and made yet another fortune as CEO of the mercenary-for-hire firm Blackwater, moved his company (renamed Xe) to the United Arab Emirates in 2011. What I mean by secession is a withdrawal into enclaves, an internal immigration, whereby the rich disconnect themselves from the civic life of the nation and from any concern about its well being except as a place to extract loot. 

Our plutocracy now lives like the British in colonial India: in the place and ruling it, but not of it. If one can afford private security, public safety is of no concern; if one owns a Gulfstream jet, crumbling bridges cause less apprehension—and viable public transportation doesn’t even show up on the radar screen. With private doctors on call and a chartered plane to get to the Mayo Clinic, why worry about Medicare?

But millions of Americans who do not pay federal income taxes do pay federal payroll taxes. These taxes are regressive, and the dirty little secret is that over the last several decades they have made up a greater and greater share of federal revenues. In 1950, payroll and other federal retirement contributions constituted 10.9 percent of all federal revenues. By 2007, the last “normal” economic year before federal revenues began falling, they made up 33.9 percent. By contrast, corporate income taxes were 26.4 percent of federal revenues in 1950. By 2007 they had fallen to 14.4 percent. So who has skin in the game?
