I visited a few cities earlier this year, Flagstaff AZ, St. George UT, and a few others and I was shocked how many "help wanted" signs were out on almost every single business. I talked to a few employees about the help wanted signs at a restaurant or two and they said nobody is applying to these jobs. I would say its a few things, some people are concerned due to covid and getting infected. Alot of people are overworked and due to unemployment being high are taking a much needed break from work. I think those are both valid reasons, Childcare is also a big one as many a spouse quit their job to take care of children due to shuttered schools and daycare, I personally know a few.
