The general population doesn’t know what’s happening, and it doesn’t even know that it doesn’t know. — Noam Chomsky
Most people don’t know they’re being propagandized in the first place, so it doesn’t occur to them to see past it. And of those who do notice, most don’t have the time, energy, skill set, and inclination to dig out the truth. It’s not impossible, but it is a lot of work. The information is accessible, but corporate media generally aren’t going to provide it.
