That seemed like an awful lot of words to describe the entirely predictable fact that the job market will pick up significantly as we shed pandemic restrictions and that workers in low-wage service jobs tend to quit a lot. A few anecdotes about people liking WFH doesn’t make the trend any more mysterious or novel.
I think we've gone a little overboard with the whole, "unprecedented times" stuff. Sure, pandemic economics are weird, but they're not "up is the new down" weird, basic economic principles apply, and we're not throwing out the whole book, just writing a new chapter.
