Occupy Wall Street Day 19: Mass march planned for afternoon; Jeff Mangum, Michael Franti, Deepak Chopra stop by

Today is Day 19 of Occupy Wall Street.

The day is going to be a big day for the movement. On postsecondary campuses, students will be walking out, oh, nowish. College students are disproportionately in debt, many incurring tens of thousands of dollars of student loan and credit card debt.

We Are Change is producing fantastic video coverage of #occupywallst. They interviewed Deepak Chopra, who discussed the economic empowerment of the poor, social justice, and how to combate greed and fear.

Michael Franti stopped by as well to play some tunes for the crowd in the We Are Change video below.

And in this video from earlier in the week, Brian, a veteran of the U.S. Marine Corp talks about why he's standing in support of the Occupy Wall Street protesters.

While Radiohead didn't make it down to Liberty Plaza, Jeff Mangum showed up for a short set on October 4.

Just how much will the Occupy Wall Street action cost the city?

"We're going to spend hundreds of thousands, maybe even $1 million on this that we don't have," NYC councilman Peter Vallone told the WNYC News Blog. "Because of these protests, we might even wind up shutting down schools and firehouses because this is costing a lot of money." The NYPD have yet to comment on the cost of policing.

Newsflash, Peter: an investment in your citizens could have prevented this.
