re: I personally know 3 middle class serving in the Middle East.
Officers and technicians that are less likely targets are often from the middle class. The cannon fodder is generally from the lower classes and of course there are exceptions. Remember, I got to see this first hand in my military years so I'm not buying into someone else's rhetoric. I'm basing my opinion on actually first-hand experience.
Now, how many are the sons of corporation CEO's, Congressmen, rock stars, sports celebrities? You'd be hard-pressed to find many there.
