All of us at ColoLines were glued to our computers Friday as we watched Sen. Bernie Sanders’ incredible, eight-hour truth telling session on the Senate floor. He was nominally taking on the Obama-McConnell tax cut deal. But Sanders’ speech was actually an essential, clear-eyed dissection of the remarkably unjust–and thus unsustainable–economy we have built over the past two decades. Josh Harkinson at Mother Jones offered some of his own greatest excerpts this weekend. But the video above, which began making the Web rounds before the speech was even over, is one of my favorites. In it, Sanders goes to what I believe to be the heart of the matter: the disease of greed. Got a favorite excerpt of your own? Shout it out in the comments.
