Is the Middle Class Doomed?

If we look at a chart of Real Medium Income Adjusted for Inflation going back to 1967, as reported by the Census Bureau in 2011, you can clearly see Real Income has been declining since the peak in the late 1990's.  In fact most Americans have seen at least a 10% Drop in Real Income based on Inflation.  If this trend continues the Middle Class is doomed and there will be an extremely large divergence between the Poor and the Rich which will spell big trouble in the future.
