Disasters begin suddenly and never really end. The future will not, in crucial ways, be anything like the past, even the very recent past of a month or two ago. Our economy, our priorities, our perceptions will not be what they were at the outset of this year. The particulars are startling: companies such as GE and Ford retooling to make ventilators, the scramble for protective gear, once-bustling city streets becoming quiet and empty, the economy in freefall. Things that were supposed to be unstoppable stopped, and things that were supposed to be impossible – extending workers’ rights and benefits, freeing prisoners, moving a few trillion dollars around in the US – have already happened.
