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?
Properly executed, a progressive tax code and representative government would seem to be the solution to these problems. (And many others.) Lightly taxed, super-rich Greed Titans with the unfettered ability to buy elections, not so much.
