I'm not sure what report your read, but that report very clearly states the following:

> Real wages fell for workers with lower levels of educational attainment and rose for highly educated workers. Wages for workers with a high school diploma or less education declined in real terms at the top, middle, and bottom of the wage distribution, whereas wages rose for workers with at least a college degree.

And that is before you start looking at issues with the CPI-U and how it's price weighting compares to real expenses faced by blue collar workers.
