That's really just the Disco Stu Fallacy of economics at play. Assuming that things _will_ get better and passing the buck onto your descendants is madness. Also how much growth has been stunted by the weight of ancestral spending?

Birth rates are declining and the cost of maintaining our infrastructure is at the point in most high-GDP locations (New York, California, etc) where obligations cannot be met and credit status changes were inevitable _before_ Coronavirus. Look at the insanity New Jersey has gone through with the criminal pilfering of infrastructure/development funds to pay pensions (aka, Christine Todd Whitman should have gone to jail).

We're looking at cascading failures in a complex system. Nobody can see enough of the picture to predict what's next or realize that it's already dead. To assume that we'll right the trend with growth will most likely require either war or (a technical) revolution.
