I am still working on my third post about employment.  As part of that I have been reading up on the rise of inequality in the US and its effects on society.  In that process I came across this interesting chart from a Morgan Stanley research report:

It shows that rising income inequality has been highly correlated with increased political polarization since the mid 1970s (found via Business Insider).

Then just a few minutes ago I saw in my Tumblr dashboard that Robert Reich is making a documentary movie about inequality and is raising money for it on Kickstarter. I just backed the movie because this topic needs all the attention it can get. The chart above shows why it presents not just an economic and moral challenge but also a political one that has in the past lead to violent social convulsions.
