>especially in the upper classes where people do not need to serve This is a often repeated myth. The upper class serves more per capita than the lower class.
Yeah, just not in any combat duty, except the rare ocassion. Combat is for the lower classes, preferably rural poor
(Former 11A here)
This kind of glosses over a lot of cultural reasons for why you find "rural poor" in combat branches. For a lot of the folks in my platoon, it was a family affair. Many were from e.g. Texas or Georgia, and had a brother/cousin/uncle/whatever who were also an 11B/13B etc. There isn't really a "preference" that the Army or Marine Corps has for poor people, but there is a cultural reason why people who like combat tend to be rural poor. This is of course my experience, and precise demographic data is hard to come by without a FOIA request.
Just wanted to throw my two cents out there. The guys in my platoon weren't the "dumb hicks" a lot of people seem to think populate the infantry.
