And don't discount COVID and Boomers....
I sat in many a Demographics projection for my job before retirement. Boomer retirement means many fewer behind them to fill the jobs. Covid pushed the retirement to happen sooner than planned for many, which made the situation happen much sooner. As well as whatever job openings were created by those that didn't make it.
Those with "bad jobs" (like perhaps back breaking pool repair or vinyl liner production people) found it easier to move up to easier/more pay. And fewer around to backfill the positions.
So pay skyrockets to attract those that are out there. And costs to you go up too.
In my pool fence search, the fancy vinyl fencing we looked at was outrageous in cost, and backordered about a year. The company only invested in one machine to make the special posts, and there was only one guy that knew how to operate it. He had a heart attack. I hear a year later they still haven't found a replacement, let alone figure out how to train him. If you can find an old production post, it has an astronomical price.
My mechanic had his top guy quit due to the physical toll the job was taking (Doctor's orders). A year and a half later, still no one to take the job, despite triple the pay offered.
My local pool store is offering a huge bonus for even part time counter staff. I even thought about it...once....
