You say that because you know that the news is fake, and you know that because it's not really that difficult to figure out at least an approximation of the truth. You know who are the abject liars (because they routinely tell outright falsehoods), and you know who at least tries to get it right even if they sometimes fail at it.

It's not that hard. People seek out the fake news; the millionaires and billionaires are just providing slightly better versions of it. They could be doing really sophisticated propaganda but they just don't have to. People are pleased to believe the most outlandish lies if it affirms their egos.

It's not that hard when you have proper education, scientific practice, understanding that you don't have to succumb to the fear pumped by those in power, and surplus time and energy to put everything in perspective in a constantly changing world. Otherwise, I'm afraid it's difficult to break out of one's echo chamber.
