Yves Smith considered the social cost of mass-marketed arms (and questioned the efficacy of armed militias in the US police state). Mark Ames* considers a counter-intuitive political cost of these Rambo fantasies:
Because it's now so deeply ingrained that owning guns is a form of radical subversive politics, the people who still engage in real politics have the pick of the litter. That first became really clear in the depths of the 2008-9 collapse, when a lot of people who thought of themselves as radicals and anarchists made a lot of feckless noise about how they were arming and preparing for the collapse and revolution. They could’ve gone out and organized something and maybe built a politics of people power or even a politics of what they call revolution, a politics that actually changed things. But instead, they locked themselves in their homes and apartments with their guns and fancied themselves political revolutionaries just waiting to be swept up. But no one came. No one bothered or cared. And really, why would any plutocrat or evil government agency bother with the suckers, all harmlessly atomized and isolated and thoroughly neutralized by the false sense of political empowerment that their guns gave them, while you do the real work of plundering budgets, bribing politicians and writing laws even more in your favor?
