There's no such thing as "corruption free" country. The US is very, very far from corruption-free, both in the government and outside it. It's less corrupt than, say, Zimbabwe, but that's not saying much. Basically one has to ask themselves a question: given that the mainstream press is wildly unprofitable (with very few exceptions), might there be a reason why its owners sinks hundreds of millions of dollars into keeping it afloat? I think you know what that reason is, Chomsky has been railing against it for several decades now. They're instruments of propaganda. They manufacture consent. They are literally no better than Pravda nowadays, although instead of being government controlled, they're controlled by five rich men. It's better than government control, but not by much.
