Welcome to the realization that private corporations have too much control over the world and the worldview and governments that are publically elected rely on those corporations and their resources and their platforms to stay in power. I just have one question that I struggle with: what should one do about it? Chomsky said "Organize and create mass movements". Does that still work today? The mass movements created uproar which led to an impeachment trial of a said individual but nothing came out of it. How would one go about to dismantle and re-structure a world where states and private firms co-depend on each other? Sadly I am at loss.
