This is about the 1000th article I have seen that mixes up correlation with cause and effect as it relates to the value of college.
They never try to compare comparable subsets (with IQs that are similar) when they make the fallacious argument that college grads make more money than high school dropouts and therefore it is a good investment.
They always forget to account for the average difference in IQs for college grads compared to non college grads. I can tell you that one factor that always seems to pay off is to be lucky enough to be born smart. A degree in Sociology is not going to cure this challenge if you weren't so lucky.
But alas, if this writer did attend the local U, he must have been sleeping during his Logic class.
