Rose Horowitch writes: “An alarming phenomenon has sprung up over the past few years: Many students are arriving at college unprepared to read entire books. The problem does not appear to be that ‘kids these days’ are incurious or uninterested in reading. Instead, young people might be responding to a cultural message: Books just aren’t that important. The professors I spoke with didn’t think their students were lazy. They saw that their students’ schedules are crowded with activities that are less about personal development and more relevant to future employment.”
