We're still in the early phases of millennials getting their first jobs and saving up to get apartments, etc. Gen Z is right there with them. The result has been a generation of the workforce that didn't learn good work ethic and skills in their teenage drug years (from approx 13 to 31). I worked from 13 on, but I have friends who didn't get their license until they were 19, didn't work until after finishing their gender studies degree, and now aren't qualified for their job monitoring the self checkout at Publix.
That is why quality has declined.
