I once manufactured some equipment that used an engine and gearbox sourced from Yurp. They rose to the top of their game in that market and became too expensive, so I started to look at Japanese and American made alternatives. The Yankee one was made in a small town in upstate MN, and I came to know the owner quite well. He was showing me once a military contract and the prototype, and said he could add a third shift when he was ready to start production. This was in a shopping area of 25,000 people. I asked him where and how he could get at least 200 more people who could pick up tools and make engines when he had over 400 already. He said: easy, the whole area is full of people (then in their 30s) who were drafted in Vietnam days.
The idea of compulsory military service is foreign to Canadian values, but I also have a close Swedish friend (another social democracy, but with conscription and lifetime obligation to serve as a reserve) and can tell you drafting a teen - EVERY able bodied teen - is one of the smartest things you can do as a nation. They end up with some sense of duty, some sense of responsibility, a trade and some discipline. Fantastic way to start into adult life.
