Thirty percent of college graduates in the United States may eventually work in jobs that do not exist yet. Proponents of a liberal education therefore argue that a postsecondary education must prepare students for an increasingly complex labor market. Rather than provide narrowly designed technical courses, a liberal education would foster critical thinking and analytical skills that allow the student to adapt to a rapidly changing workforce. The movement towards career-oriented courses within a liberal education has begun at places like Dartmouth College, where a journalism course combines lessons on writing style with reading and analyzing historical journalism. An American survey of CEOs published in 1997 revealed that employers were more focused on the long-term outcomes of education, such as adaptability, than college students and their parents, who were more concerned with the short-term outcomes of getting a job.
