Earlier quoted context omitted.
> If there is an _actual_ shortage, increasing pay does not just fabricate workers. Sure it does. For some people, it means switching from stay-at-home parenting to daycare financially sensible. For someone on social security, it might mean temporarily going back to work is more attractive than it was. People go from not seeking jobs to seeking jobs all the time.
Demand scaling doesn't happen instantly. For instance, how are you going to get new CNAs (even reupped certs) right now when the schools are closed?
The definition includes a vast set of un-credentialed workers; people at meat packing plants, grocery stores, cleaning staff, etc.
(Again, there will be licensed CNAs not working due to the cost of things like daycare. Raising wages changes that calculus, too.)
