As having enlisted in the Seabees shortly after graduating high school in 2010 I can reluctantly say that at that time there were guys that we called "lifers" (guys that remain in the military as long as possible) by us guys that decided to do our 4 years and get out, which I did. A lot of "lifers" confided to me that they couldn't make it on the outside, they enlisted for the benefits, housing. medical care etc for them and their family. There were some "lifers" that needed a structured life, someone to tell them what to do, when to do it, what to wear, when to eat etc. There were even some alcoholic "lifers" who wouldn't be able to hold down a job on the outside. But let's give the devil its due, they were /are brave men and there were "lifers" who originally enlisted for purely altruistic reasons.
The military has changed rapidly in the past 15 or so years. No one wants to enlist nowadays since the military seems to be catering to the LGBQ crowd. Just look at that fat transgender who has the title of Assistant Secretary of Health and Human Services and and has the title of Admiral and wears a uniform and also the Federal government has become so corrupt, more so than in years past so that clear thinking individuals just shy away from enlisting.
But let's not throw the baby out with the bath water. I must reiterate, there are brave men that sacrifice unselfishly and enlist because they feel an obligation to serve their country regardless what others may think.
If the draft is reinstated and in my opinion it most probably will if things keep going the way things are going and the draftees perceive that they are being forced to serve a corrupt government then there might be someone even more dangerous than the supposed enemy, and that would be a disgruntled well trained soldier holding a rifle.
