Why can't people learn?

Main stream media has become (for the most part) our obsession and we let go of our desire to learn. We have sadly become lazy, believing what they tell us, instead of confirming. So this is how dogmas on major controversial topics come to be. Not only that, but I think we have become too self centered as a whole and expect too much from the government without knowing of it. Simply said, why do we need to know who feeds us? As long as we're fed. We're very decidable and I think that's why we care less to know the truth as long as the truth about any topic is easily achieved. Sadly, we're just lazy. I don't think the schools or teachers are to blame though. The school systems themselves are failing right now because politicians and lobbyists are trying to make as many of them privatized in order to earn more revenue. I think that corrupt politics is partially to blame for our school system failing our youth. As a high school student, I think that most people are very enlightened and knowledgeable on these topics that you described, but our means of publicly speaking of them is handicapped and restricted because main stream media and dogmas arriving from them over shadow our reality. You'd be surprised how much potential the youth has today, but it's being limited more and more. Don't know if that answered anything you asked, but I simply wished to state my opinion on the matter.
