There is no binary choice of “next Great Depression or mass death.” The government can support people while they take the absolutely necessary steps to contain coronavirus, allowing them to pick up where they left off once sheltering in place is no longer necessary. Other, smaller countries are taking measures that could be models here and wouldn’t require any new programs or political infrastructure — just pumping money through existing channels. We have the technology (i.e., money). Lives and livelihoods do not need to be destroyed.
But left to itself, the invisible hand is going to inflict a Great Depression on us as punishment for doing the right and necessary things. The invisible hand will destroy careers and businesses and whole communities full of people who did all they could to save lives. How do you expect people to sit back and take that?
The Financial Crisis already inflicted a huge system-wide economic shock on people who were ostensibly “doing the right thing” (buying a home), and that was a huge blow to the legitimacy of the system. Coronavirus is on course to do even worse. And establishment Democrats are doing their level best to guarantee that once the legitimacy of the system — not just the neoliberal order, but perhaps the Constitution itself — is destroyed, the extreme right will be the ONLY organized force in a position to pick up the pieces.
