Except that the notion that everyone's doing better than you DO push people into downward spirals. And while the lesson should be that you shouldn't compare yourselves to others, it absolutely does happen in law school (http://www.canadianlawyermag.com/article/i-failed-in-law-school-and-you-can-too-2817/) and it would be strange to call it a "ridiculous" concern. Counterproductive, maybe.
By this token, people who pretend to be worried about high grades at a good law school, by their pretense, may push others into a downward spiral. And, treating ridiculous concerns seriously if it's not a pretense, may push that person and others into downward spirals. Better to dismiss such ridiculous concerns, I would think, as ultimately being more reassuring than enabling the tale of pseudo-woe.
