Just watched NBC Nightly News and the lack of staff in tourist areas was one of the stories. Businesses on Cape Cod (as well as Michigan, Maine and California and others) are having a very difficult time finding summer help again this year. I happen to live on Cape Cod and in Naples FL as well as vacation in Maine and have experienced first hand what Covid has done to the service industry in these places since Spring 2020.
Sadly some people think they’re just getting screwed and the glass is half empty. I’ve witnessed what’s going on for two plus years and don’t think what the OP wrote about Celebrity is true: “I’m sure that there are financial analysts in Miami are thinking that people are sailing on the Summit with this level of staffing, let’s extend it to the rest of the fleet.” Everyone is hurting.
