I am amazed, though, when I fly with certain mid-seniority CAs, and when I ask if they want to bail, they say "Heck yes, I can't stand this place." Then I ask them if they're updating their apps and/or are attending job fairs.

I've heard variations on the following reply so many times:

"Update my apps? Yeah, a couple years ago. Job fairs? Heck no. If they want me, they can call me."

There clearly are folks who want to move on but aren't putting in the effort...but can't bring themselves to admit that they're going to be at OO until they retire.

Which isn't a bad thing by any means. Everyone's priorities are different. If you live in base, are near the top of the seniority list, and have a side business or a spouse with solid income, it may not make sense to trade that for commuting to reserve at the bottom of a legacy's seniority list.
