Are we talking US military here? I think I recognize the pattern you're talking about when you say:
> I have lots of kids (18-20yo) with mental health issues that are not helped by being allowed to take time off so casually. Our mental health experts want to keep people working because having them sit at home drinking/gaming does nothing. I have seen kids actually react well to increased "stress" on the job. Think basic training stuff. They are worked hard, go home tired and then actually sleep. Sending them home not tired leads to drinking and late-night gaming sessions after which they do not sleep and come to work the next day like zombies.
You aren't actively doing anything. You're saturating their day so that they're distracted from whatever underlying problems they face. They're too tired to deal with them so they sleep and repeat. I'd be curious to see your solution play out in the ten years post separation, but the VA may be ahead of you. For context (if you're not American) TAPS is what you take as you separate: https://benefits.va.gov/TRANSITION/docs/pstap-assessment.pdf (Section 4.C should have some relevant quotes).
I remember at some point a Navy Corpsman explaining to me that the goal of Navy medicine isn't to make you better, it's to keep you in fighting shape. Fighting shape doesn't need to be the best or most optimal shape, just enough to do the job the military needs you to do.
