Many ambitious students are striving to make a career in the humanities (probably like this author), to go into investment banking, or to get into an elite law or medical school. These fields are so competitive that it’s not worth risking taking classes you might not get an A in.
This results in students filling their schedule with easy classes and professors and maybe not taking the classes they are interested in. Or worse, punishing students who don’t do this.
Some of the smartest people I know were 3.2-3.5 students because they did not play the game and took challenging classes across disciplines. Conversely I know some absolute morons who got I-banking jobs at elite firms because they only took fluff classes
