Now, what I have always found interesting is that the president's incessant detractors have always touted that the reason Occupy Wall St. was born was because "Obama failed us" and they believe that Occupy is some sort of referendum on the president. When presented with facts that show that the president has voiced support for Occupy and that many of his strongest supporters also support Occupy, of course they just shrug that off. Doesn't fit the preconceived narrative, you see.
What is most striking about that Vanity Fair article is that they interviewed dozens of people that were there when Occupy was conceived and first put into action. These folks do put some blame at the president (angry that bankers weren't put in jail) and logically, put MUCH more emphasis on the overall corruption and inadequacy of the American political system (which has been going on for decades longer than this president has been in office). But really quite startlingly, some of them also ascribe some blame squarely on the political left for many of the reasons that you already noted.
The left had been chattering on about revolutions for a long time, but we’ve basically been howling at the moon. And then, all of a sudden, a bunch of young people using social media were able to mobilize not just 500 or 5,000 people, but 50,000 people. They inspired us with their courage and with their techniques.
The left has the ideas and the heart but not the MEANS to implement the change that they seek. Apparently, it was this frustration with the political left that was the impetus (along with many other factors) that led to the creation of Occupy. Folks really need to understand this the next time that loud handful of serial malcontents tries to drop everything at the feet of this president -- as usual.
