Tyler notes Federal Reserve PhD elitist Kartik Athreya's research on bankruptcy law (he's the guy who writes non-PhDs make econ debates less fruitful). Then, as the 'other side', suggests blogger and non-PhD Megan McArdle. Equivalence implied.
What makes this all so harsh is I'm sure it was unintended. Kind a like when a boss says of a valued employee on her retirement, that she was the 'best secretary he's ever had', when she thought she was an analyst.
