Is Revolution Brewing in the US?

According to a recent study revolution historically takes place when the level of inequality reaches a tipping point. The scale, used for decades, that rates inequality is the GINI coefficient with total equality being a 0 and total inequality a score of 1. The highest score in the past belongs to ancient Patrician Rome with a score of .59. So where does the US stand? Are we getting close to that.59? The GINI score in the US today is .81, one of the highest in the world. I'd say revolution is inevitable. What do you think?
