This is my opinion, but paying for soldiers to be educated may cost money, but I suspect as a whole the GI Bill actually generates wealth. I am all for an educated population.
I can 100% say the sectors of the USA population that are uneducated are the sectors we are spending the most money on in terms of welfare, crime, etc.
Personally, I would be all for stripping Pell grants, etc from students and make them "earn" their govt assistance in University by serving in the military (the problem with this is the military doesnt want that many people). But the alternative with all the govt "grants" for college is the students are getting handouts and not earning it.
Twice a week? 14 times a month?
Many of the truths that we cling to depend on our point of view.
