Why does the US media get the big stories wrong?

The Atlantic has a long sad story about it.  I have a simplier explaination.  The media is staffed with crusaders, zealous fanatics who see them selves as prophets come to save  the world.  Woodward and Burnstein "All the President's Men" is their self image.  They could care less about truth, informing their readers, all they want to do is win.  And they will do a lot a shady (not quite outright lying, but close) stuff to win. 
   These people float thru college doing journalism majors and learning nothing of substance.  No American history, no European history, no math, no physics, no chemistry, no statistics, no Shakespeare, no foreign language, no philosophy, no biology.  No practical skills such as carpentry, auto mechanics, hunting, fishing, farming, or even light bulb changing.  They come out of college shallow and ignorant.  They may be fairly good at slinging BS, but they don't know nothing.  Naturally the stories they write are largely a waste of the reader's time.
