I'm not sure school teaches you discipline rather than filter out the people who don't have discipline by making them unable to graduate unless they ingest all the useless crap taught there (together with the useful stuff). If you can't teach an employee to be more disciplined when you can put their job on the line, I don't know why you'd think that even the crappiest school knows some secret to teaching discipline that you don't. Of course that means if you're hiring and need somebody with "discipline", maybe hiring a CS grad makes sense. But if my hypothesis is correct, a high school student probably wouldn't benefit from going to university to learn "discipline". Not that I think putting up with crap is something I'd want to actively learn.
