“What we’re experiencing is also the net result of decades of policy choices starting in the 1970s that emphasized consumer sovereignty over citizenship. The consolidation of power into the hands of private equity financiers and monopolists over the last four decades has left us uniquely unprepared to manage a supply shock. Our hyper-efficient globalized supply chain, once romanticized by men like Tom Friedman in The World Is Flat, is the problem.
