I don't think the kind of foundational change that is needed to solve these issues has ever been done in other ways. If it can be done, it's much harder than just letting it all burn down. The people at the top of any system are not willing to change it without a fight.
If you think "the people at the top" suffer the most during a world war you're deluded. If you're willing to do that because you don't like ads or because girls aren't replying to you on dating apps, no words.
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.
