Amazingly, you seem to have missed the entire point. I'll help you out apples.
It doesn't mean we're supposed to hire people who don't show up. We're not quite there yet, but if we have to endure four more years of Dementia Joe, we'll get there.
It means that employers are so desperate to hire anyone with any qualifications, that they've had to lower the bar and hire anyone who does show up. Knuckle draggers, dribble cup wearers, etc. are probably included.
