I suppose we could tie it all to the upbringing we were taught in the givernment institutions aka "Public School." In where we are taught to obey our teachers and governing authorities without question. Same with our parents. We are taught how to do things but nowadays we are rarely taught WHY we do it in a certain way.
I would blame this sort of blind faith as being the source of naievete that has become commonplace in the U.S. Now with the advent of bloggers, people are waking up and are turning to other outlets for their news. People with no real agenda other than for the facts on the ground as they find them.
Contrast this with the mega-corporation news outlets and the news anchor who gets $100 million a year and tells you what is news and what isn't, or the blue-collar blogger who earns $50k a year who tells you what is happening and where it happened. (how's that for a run-on sentence?
). Who would people be more willing to trust if they make mistakes? And who would they retaliate more harshly against for trying to cover it up?
