No, I think he has a point.
It's important for society to participate in our wars - at home and the military. During WWII we had bond drives and ration cards, victory gardens, etc..
I think these are very very important, regardless of their actual value to the war effort.
I think it's a mistake to not include things like this in the WOT.
You haven't sacrifices anything. If you are serious visit a recruiter.
I wasn't around for the WWII years, but I've seen enough movies and heard enough from my parents to know we're not rationing rubber, sugar, cloth, gas, meat, steel and a number of other things we take for granted. No, the vast majority of us haven't sacrificed a thing, certainly not on a daily basis.
