They don't suffer the most, but the point isn't to make them suffer. The point is to change the system. If the current system feels unfair or wrong in some way, people will want to change it. If the only way to change it is war, and if enough people want change, then war is what will happen. The war might make things a lot worse, but at least people are worse off together and are forced to take care of each other in a way that we haven't in a long time. The selfishness will be reduced, communities will come back, and a better system might be the result.
