It was a nice surprise to see teenagers working in my local brewery this past weekend, collecting glasses, clearing and cleaning tables, etc. They were probably between 13 and 16. Not allowed to serve alcohol until they are 18, and can take on the personal legal responsibilities for Responsible Service of Alcohol.
Most jobs for teenagers here are in fast food service - two of my friends have mid/late teenagers working these jobs. Most jobs in retail, at least near me, seem to be taken by adults.

Most people are not self reflective reflective enough to notice. Need to trust the studies.
Far more plausible than the AI ideas.
I find it far more likely these are smart people running without oversight for years pre-COVID, relying on being smart at 2am change windows. Now half or a full std. dev. lower on the IQ scale, hubris means fewer guard rails before change, and far lower ability to recover during change window.
