Sadly in the USA we have poor towns where all of the industry is gone and so the young men join the military as soon as they are old enough, the military is the only job provider in some areas. But, with the military the young men get to travel, plus they get a free education and job training, and they get home loans, and they get business loans, and they get medical insurance, etc. Also, in some areas they set up businesses by the military bases and that is the only opportunity in some areas.
My home town built the Space Shuttles, and lots of top secret planes, and Edwards Air Force Base is a major job provider in my home town, along with NASA, etc. Aerospace and defense spending helps to employ my home town. And some of the planes that we are sending to Australia such as the B2 Stealth Bombers were built in my home town.
Salute,
