Mayhaps the problem lies in specialization. In my days at college, journalism majors (or their even weaker counterparts, communications majors) weren't exactly the broadest intellectuals around. They were okay at learning their crafts, I suppose-- forming graphs, prioritizing info, remembering four of the five W's. But because they never seemed to show much interest in things like political science, history, hard sciences, economics or other the other things they would ultimately end up writing about, they never got the fifth W-- the "why."
Sure, those with street smarts can be good at the regular crap that fills the papers-- who shot whom, who was arrested, who ended up in the morgue and under what circumstances. They can write authoritatively on missing pets, troublesome neighbors and the occasional serial rapist. But get into anything remotely smacking of public policy, and they are clueless.
Clueless and often lazy. They learn to rely on sources with agendas who spoon feed them biased half truths, untruths and anti-truths, which they either don't know or don't really care are accurate.
Thank god for blogs. At least there you have people who have the underlying background and knowledge to know what they are talking about. And eventually, they can figure out how to write effectively.
No wonder these MSM clowns are so snarky about them. Just the way the Legions were snarky about the Vandals.
