I've gone through the first class line lots of times when it was short. In Atlanta airport they actually pull people from the main lines to the first class lines if nobody is in them. I do believe your correct that they do not pay extra.
But the airlines all "request" that there is a first class lane to provide more value for purchasing the first class ticket.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
