Some day.
I doubt it’s the only ‘school’ that has an explanation. That there are cycles in the economy isn’t a very strong statement. Nor does it seem to apply here because this is a different cause than one underpinning a typical business cycle.
Until this virus is wrestled to the ground somehow (e.g. distancing, sterilization, vaccine, herd immunity, etc...), we’ll continue to see mitigating effects which distort the picture of normalcy pre-2020.
See other comments of my explaining the virus is a pin that burst a bubble already there.
