Living in capitalism is kinda like being a gladiator: if you don't kill your opponent, he is certainly going to kill you. Meanwhile there is a whole arena around you, where everyone is expecting someone to be the winner. Under those circumstances is pretty hard to step back and say: "Okay, let's stop and take a different approach."
I really like your vision of the future though! That would require us to leave the arena in droves, but as you pointed out, today we no longer believe we can bring about positive changes through war and lies (or I would certainly hope most people don't), so change is possible.
