It's not that they'd pay individual employees more, it's that they'd hire more workers to account for the fact that their existing workers are tied up doing extra verification.
I wasn't flying 25 years ago but I'm not sure what you mean, or how that's relevant actually. The point is just that it takes them more time to do the "extra screening" if you don't have your ID than the standard screening if you did have your ID.
