Science is merely a process by which an external reality can be observed and verified, nothing more. Science can document as accurately as possible, given our personal failings, how the world is going to hell in a handbasket, but in and of itself it can’t actually change much of that process.
That process is governed by ruling classes and power hierarchies that run on threats, force, human conformity, appeals to emotion, widespread indoctrination, and so on. Science can help understand those processes but again it can only describe them.
Science is about knowledge, not action.
Changing things will require a process of revolutionary struggle; ruling classes never voluntarily relinquish power just because it’s the nice thing to do (and you built and enunciated a convincing fact-and-logic based argument).
