And I'm not implying that all young guys are "without direction".
History tells us that those with direction will go to school at Kettering (as an old GMI guy, I struggle with that) or maybe somewhere with women, start on a career path in the trades, or otherwise start "life".
Others mill about and "fail to launch" in life. These guys need that additional socialization the military provides. I know many people my age and older who's lives were put onto a good path by a stint in the military.
This is the Pub. Leave common sense at the door.
