Suggesting that signing up to "protect and serve" reduces the value of your life to 1/10 of someone who didn't is...insane. Generally speaking, the suggestion that a person's profession influences the value of their life is abhorrent to me.
Richer people have not fought in wars, since forever. Why? They can pay someone else to go die for them.
In modern days, look at the socioeconomic status of people that sign up for the U.S. Military. They come from poorer and less educated than average families. That is basically what military pay does... you start at some level, and slowly raise it until you have enough people willing to risk their life to earn it. Everyone has a price.
