Lots of good points made here, and I too am worried about bammy as CIC. I am now in the reserves, and wonder every day what will happen.
With that said, I still encourage anyone to join. But it should be his choice, with no pressure either way from his parents.
As far as getting a MOS that transfers to civilian life, its a trade off. I was an artillery and naval gunfire scout observer (forward observer in civilian lingo). Not much civilian demand for that. Aircraft mechanic and things like that are in more demand.
However, there is nothing like the pride of a combat arms MOS. I wouldn't change my 4 active duty years in the Marines for anything, even if it would help me get a better job after college.
A DD214 on your resume can't hurt, regardless of branch or MOS. Especially gov jobs and that 5-10 points vets preference.
