Mankiw is an economist at Harvard.
Why he's there, I don't know.
But 10% of his class (the ones who are probably going to get C's and D's) walked out to protest the conservative nature of economics. (though I pine how many classes would even exist if students walked out because of liberal bias).
Now, understand something about economics.
It's largely math based.
So if you add 2 and 2 and get 5, you are WRONG. mathematically, factually WRONG (but then, hey, at least you're on the B honor roll at Harvard).
Additionally, it is largely logic-based as well.
Evil things such as "if nobody works, we'll all starve" or "you can't afford that because you didn't work hard enough to earn the money to pay for it" unfortunately do come into play and are presented as facts.
Naturally idiots have a hard time with math and facts which is why I will guaran-freaking-tee you that all of the 70 students that left are not in a STEM field and will further go onto produce either nothing in their lives, or worse, run for public office or join some crusder non-profit outfit to tell others how to live their lives.
In the meantime they'll be a bunch of cry babies that don't like reality.
Any takers to see if they part of the 1%? I mean, privileged, spoiled brat Harvard students? Any takers? bueller? Bueller?
