I spent 22 years in the USMC and I cannot think of a single person that joined the Marines or the Navy to escape poverty, maybe I was just put in special privileged units so that I wouldn't have to see that sort of thing.
Remember the primitives and their habit of "projection," attributing their own feelings and motives to others.
Possessing only base, carnal, materialistic motives, things such as "doing good," "serving one's country," "growing up," a desire to see the greater world outside, "becoming a better person," are alien to them; they have no idea.
They can't possibly imagine anyone would serve in the military for any reason other than why they'd serve too, for a free meal ticket.
