One could make an argument based on what we've seen during COVID19 so far that very large sections of the US economy are not genuinely viable. They've been fabricated out of the whole cloth that we call debt, they have almost zero resilience in the face of negative economic factors, and they participate in widening income and wealth inequality by not actually being the locus of viable family-supporting jobs.

Nobody has wanted to acknowledge that so much of the US economy is a house of cards. COVID19 isn't forcing people to do so, but is making it much clearer.
