It appears you don't understand mine. Data points are in research papers, in dark corners, statistical banks blah blah , charts are used to summarize and give visuals of mountains of data points. That's good enough.
You want to play expert and analyze research papers yourself go ahead. i'll let experts i trust do a better job for me. A better job than either you or i could do ourselves.
i even gave you some credit for posting the paper that Krugman cited.
