At least he or she knew what the minimum wage was...
The facts that education happens when the moment is right for the students--not when it is convenient for professors--and that often school-time is not the right moment for students make teaching heartbreaking, yes. And students waste--from our perspective, at least--a lot of their college years. For someone who has done none of the reading, to claim that the Manifesto is a novel seems a not unreasonable guess. And I know that I still confuse there/their, principal/principle, and great/grate. So I can forgive a "Unighted States."
But don't exaggerate. Someone who hasn't spent a huge amount of time reading microeconomics wouldn't know that the opposite of "inferior good" is "normal good." They might think of incomplete, inopportune, inattentive, inapplicable, insane, and--naturally and intelligently--generalize and go from "inferior" to "ferior". And the reasons for the collapse of the left in the late 20th century--the "forward march of labour halted," as Hobsbawm put it--are deep and complex, and are reflected in rather than springing from the academe.
But Yosemite is absolutely glorious.
