Over the weekend, a YouTube video breaking down income inequality in America went viral. As a reader of BillMoyers.com, you may have been aware that the disparity in wealth between the richest one percent of Americans and the bottom 80 percent has grown exponentially over the last thirty years — but the video, posted by user politizane and relying on data from a popular Mother Jones post, focuses on the difference between the ideal disparity that Americans would like to see and the reality.

The gap is a lot larger than many informed Americans realize.

Watch the video.

The video drew on statistics also discussed in a 2011 Mother Jones article, “It’s the Inequality, Stupid.”
