The "details" _are_ the underlying story, and if they're effectively the same as what the graph purports to present: why not present the correct graph? For a b

  I disagree the details are not the story. If the perfect information was available it would almost certainly tell the same story: the cost of college education is rising rapidly relative to the income benefit of that education. Do you disagree? A details analysis could potentially allow us to understand the magnitude of this gap but it is certainly both positive and significant. The biggest error in the graph is using total debt versus median or average debts since we know the number of students has increased. I wish he had used median debt or median cost but as I noted above both median debt and cost has roughly double over the past 10 years - so the story stands. Part of any good analytical education should include the skill to form judgements with imperfect, incomplete and/or inaccurate data. In the real world it is very rare you have a perfect experiment that gives you perfect data. That said I agree we need better analytical education. We also need better data.
