1/3 of the problem = the media filters explained by Herman and Chomsky
2/3 = the Democratic Party, which either goes lite on these (Haliburton) or helps bury them (the legality and wisdom and honesty of the Iraq crime; the real taproot of economic trouble, etc.)
Quibble about the percentages, but I don't think it's a complicated new explanation we need. It's power, man! PBS is tiny and subservient, and we're governed by a two-winged Business Party.
