AVI gave us a free mini-post in his comment, here:
Journalism at present involves a great deal of believing that you know other people's motives. We are told that OWS has some legitimate complaints. Not because very many of them are actually clearly articulating legitimate complaints, but because journalists can think of reasons that people might be upset that sell better. This is common in the type of anti-American rhetoric we get explained to us: "Well can you blame them? America has done blah, blah, blah..." Those are not, in fact, the reasons why foreigners hate us. They are the reasons liberals hate us. They project this crap onto others all the time, because they really are that narcissistic and tribal.
So helping out OWS is just a natural extension of that. They are "giving voice to the voiceless, to the inarticulate rage of the disenfranchised, who deeply resent the inequitable distribution of wealth that allows people with unapproved attitudes to...oops, I mean, 'that saddles future generations...' no wait, I'm looking for the right words here... 'that finds a way to make a fortune even in hard times...' damn, this is hard..."
Because they see it as Us vs. Them, zero-sum, for cultural hegemony and prestige. That is the subtext.
Hegemony, prestige... and cash, AVI. OPM. That's what they really want.
