I'm asking this as a genuine question, not as a hot take.

Where I'm coming from:

My husband and I went to dinner the other night -- apologies from the waitress on being shortstaffed. A sign on a local store asks for patience with the lack of staff. The people staffing order pickup at a nearby department store aren't enough to keep up with orders. At my most recent doctor's appointment I spent almost 45 minutes in the exam room waiting to be seen (for an appointment I had to make over a year ago). A few hours after the appointment I went to pick up a prescription, and it hadn't even begun to be processed yet. There was only one cashier working, and she was having to jump between the in-person line and the drive-thru lane. At my job we don't have enough substitute teachers, so we're dependent on regular teachers covering classes during their "prep" periods.

This is merely a recent snapshot from my own life that I'm using as a sort of representative sample, but it feels like something that's been building for a while -- like something that was going to be temporary due to COVID but has stuck around and is now just what we're supposed to get used to. I remember that I used to keep thinking that understaffing would eventually go away over time, but it seems like it's just standard practice now?

Is this something specific to my experiences or my local area (I'm in the US, for context)? Are other people seeing the same thing?

Assuming it isn't just me, is there anything out there besides anecdotes that addresses this phenomenon? I don't want to lean solely on gut reactions, but I also can't deny that nearly every business I go to seems visibly short-staffed all of the time.
