<p>I think Michael Sandel should turn away the 780 undergraduates who flock to his class every year and only admit 20. It might spark a riot, but, the 20 undergraduates in his class would have both a famous prof and a small class.
Jonathan Spence at Yale should have similarly limited enrollment in his Chinese history class to 20, instead of letting 400-600 students take it. The rest could always read his books, right? Thing is, our Yale tour guide absolutely raved about that class and she was not an East Asian Studies major.</p>
