The average age for enlistment is 18. We frequently will let people enlist before that (at about 16 with 2 years of boot camp with parental permission). That leaves 7 years of service. and theres plenty of them that live even longer. i never said they would contribute for a long time. but they could do all the jobs that those of us with normal mindsets find to repetative and boring as they usually dont. 7 years of military service is more than most who sign up put in. and if they start working as stock clergs and manual laborers at 16 (youngest age legally allowed, then u are talking about 10 years of cheap, effective labor. personally, i think that is a contribution. It means we dont have to out source that work and the money stays in the states.
