Nice graphic showing jobs losses and job gains in the last 4 years cross-referenced by wage level. Where did the Middle Class go??

Here is a nice summary of job losses and jobs gained since the advent of the Great Recession.

They are broken down into wage categories (High, Mid and Low) and by losses (dark blue bar) and gains (light blue bar).

High wage jobs are back to even. Mid-wage jobs have taken a beating.  Low wage jobs have come back with a vengeance.

Is this a textbook case of "hollowing out of the middle class"?
