I laughed at the study comparing twins with different schooling. Is that supposed to demonstrate anything except that success isn't entirely genetic? Personally I think it's unwise to say that college is absolutely a positive investment. There are a lot of factors involved: the two most obvious are cost of attendance and desirability of degree. Is it worth it to pay $15,000 a year for a STEM degree? I think so. At least, my personal experience indicates that this was an extremely wise financial decision. What about paying $15,000 a year for a degree in literature? Probably not so wise. Also, the income comparison provided is a little misleading because it only includes full-time year-round workers 25 and older. This isn't useful for a prospective college student unless they also know the probability that they will actually be a full-time employee at age 25. If unemployment rates are similar for both demographics, the difference in expected income would be less. On the other hand, if college grads are more likely to be full-time workers, the article's statistical argument would receive some much-needed strengthening.
