I think some of it is everywhere. If you go to any university, you will find a certain portion of that. Is it worse at MilCol? Studies have shown that it is, or has been, progressively worse than in other areas, and there's more work to do.
There is a certain reason for that. They are taught to be elite. They are told, over and over again, that they are starting in a pole position, and they're the best and the cream of the crop. When you get told that enough times, you start believing you are above any reproach, and you start derogating from rules and regulations.
I don't think it comes from schools, necessarily, or from any particular place. I think it's perhaps the way we've selected them, and then groomed them to believe they are the best.
