The root of America's deterioration is economic. What matters the most, at the proverbial end of the day, is whether people have the means to keep their families together, housed and fed. Many don't. For the past 20 years, liberals have maintained a pep rally for the middle class (in the process of being updated to "working class"), ignoring our poverty crisis. Their "inequality" discussion is restricted to the gap between the workers and the owners -- in a country that lost over 5 million manufacturing jobs alone since 2000. The great majority of poor are white. If mentioned at all, they are portrayed as a collection of ignorant, beer-swilling, right wing yahoos.
Years of work have gone into using stereotypes to divide and subdivide the masses, pitting us against each other.
