.. and a large amount of bullying, harassment and occasional suicide problems?

(seriously, "bring back national service, but I don't have any facts" is a terrible argument for HN)

An environment where you are being taken care of for every aspects of your life: when to wake up, what to do, what to eat, how to dress, how to talk, when to relax and when to get to sleep again ? Problems would get back as soon as one gets out I am afraid.

Work ethic can make a huge difference though. To one degree or another we all slowly figure out what to do with our lives. Doing it with a drive that's been drilled into you can be a blessing, and a lot of the lessons apply well throughout life; cleanliness, routine sleep schedules, being respectful.

I think there are a lot of potential issues with service, but if you're feeling lost in life, at least you can pick up some habits that should help long term.

You're not being taken care of. You don't learn to make all of your own choices, but it was exactly that problem that destroyed me. I suddenly had all of these responsibilities and decisions and things I had to deal with alone, and I ended up throwing away my full scholarship to a private school by playing WoW all day instead, surrounded by coke bottles in a dorm room.

Military discipline would have been great for me because I would have had some functional baseline. Unfortunately, there is no analogue to "just join the military" for the disabled.
