The way things are going in our country, this too will be allowed. What ever happened to the Amateur Athlete v the Pro Athlete? HS, College, and other "educational" institutions used to provide "amateur athletes" for the Olympics, World Cup, and College Sports, now they seem to want their scholarships, additional "Booster" benefits, and now the Holy Grail "MONEY", all the while attending an educational institution.
I can see it now, the "star" QB reports for his Sophomore year driving a Bentley, and having an off campus home (for use on liberty). Maybe the "lesser" athlete will just have a new Jag, and enough money to call out for food every meal while his classmate have to take a loan for a car and have to eat in campus dining.
IMHO, if the military adopts this regulation it will likely create a "Class" social structure, with the haves and the have nots. Could cause a LOT of problems!! Scholarships are supposed to be based on need? So does anyone getting money from endorsments now have to pay for school and services?
