All 60-70 of them? That’s how many English majors graduate from U Chicago each year nowadays.
In any case, a quick perusal through the enrollment of classes at UChicago which deal with “classic” White Male authors, and few of them were fully enrolled. That is exactly what you would expect when a major has that few students, and they are the only ones taking these classes.
The courses about Shakespeare, Milton, and others are not any fuller than any other classes, and are generally smaller classrooms, not huge 50+. The only White dude who can fill a classroom is not even a native English speaker - a class on Nabokov’s Pale Fire pulled in 87 students.
Actually, the only reason that some of the old White dudes have as many students as they do is because there are requirements for a course on literature composed before 1650. So it’s Chaucer or Shakespeare. The requirement for a course on literature composed between 1650 and 1830 will get another Old White Dude, or Jane Austin, or somebody else that the student already knows.
So no, students are not thronging to classes, clamoring to learn literature written by White Christian Men.
Moreover, English Departments have been losing enrollment for decades. After a peak in 1970-1971, when there were almost 64,000 graduating English majors, which was around 7.6% of all degrees given those years, it dropped by 50% in the early 1980s, recovered to around 4.7% of all graduates in the early 1990s, and since, the proportion of English majors of graduating undergraduates has dropped steadily, to around 3.7% in the early 2000s, to 3.0 in the early 2010s, to less than 2% in 2018-2019.
So fewer and fewer students are actually becoming English majors. It is dying field, and teaching the Wisdom Of Old White Men is doing nothing to keep it alive.
Revised to add: U Chicago has some really cool and interesting coursing in their English department, and many of them seem to be drawing a good number of students. So they are not relying on the same old set of Old White Dudes to keep up interest in a changing world.
