Looking a little deeper into the report we find that the earnings of full time workers (see page 15) only increased by 1.5% for men, and 2.7% for women. Substantially less that the 5.3% increase in median income that is being touted.
My conclusion is that jobs aren't paying much more at all and that most of the increase is due to an increase in the number of workers per household.
