More support for "The more you learn, the more you earn"---BUT is it a good thing??

The graph below shows the differences in pay, in terms of educational attainment, someone in 1979 earned with someone in 2009.  There are lots of inferences you can draw from this data (if you read the accompanying link you will see some).  Can everyone go to college?
