You genuinely have no real grasp on the world we live in. Yeah, at this point in time, that is idealism. We get there the same way we got here, one bite at a time. You don’t change the programming of society in a blink without destroying the system entirely, and even then it’s still not how it works, there is nothing everyone universally agrees on and there never will be. Life, as they say, is a series of compromises. There is an inoperable lack of societal awareness and pragmatism to your ethos.
Those who learn history are doomed to watch thise that don’t repeat it, as they say.
