This is what some might call a WTSHTF scenario (I'm not good with acronyms, but I think it means something bad), or an anarchy state whereby small regions will band together for common defense. Whether it be a rudimentary (albeit modern) version of feudalism or ancient Greek-style polis or small geographic regions that unite for survival -- it matters not. Small government will be achieved. And that would be the antithesis of what Cloward and Piven want.
Politics and war go hand in hand!
