College track kids won't go. Sorority broads, beer pong and football games >>>>>>>> basic training. Some might if they want the military to pay for their education.
What you're left with are high school kids that may not want to attend a 4 year university. Some kids do trades....so they probably go down that path.
There will always be some kids willing to join the military but many more that just aren't cut out for it.
I was 145 lbs and under 10% bf in high school. Definitely in shape but had plenty of financial aid and college acceptance letters. There are A LOT of kids like I was but honestly the best prospects are going to school.
Wait until Universal Healthcare and free college get passed.
Then the military recruits will go down to Z-E-R-O
