> It fueled extremism and populism, both on the left and on the right.

I think you're confusing the Occupy Movement with the housing crisis itself.

Any anti-establishment/libertarian right-wingers would have already gotten energized years before by the Tea Party movement. Even Ron Paul's million dollar "money bomb" in donations happened a few months before Occupy. And what's the path from Occupy to right-wing extremism? Even on Fox News Occupy was a short-term blip.

The "one percent" slogan made its way directly into Bernie's campaign, so that tracks with what I assume you're calling left-wing populism. But what do you mean by "extremism" here? If it's violent extremism I don't see the connection. And if it's left-wing anarchist movements, have those grown in any significant way since the 2010s?
