No, I'm not proposing that at all, however, we certainly discourage people from having children at a young age. Military leadership could fairly easily adjust its recruitment practices, it relies far less on physical aptitude nowadays. Regardless, I don't really think this tangent is relevant to the discussion of college education.

You can shift mean college attendance age in a myriad of ways. Off the top of my head, bring public universities back under federal funding, reduce the for profit motives. Then start preferentially admitting students with a year or more of work experience as well as the current academic standards.
