Members of Generation Z are anxious to pick majors that teach them marketable skills. According to the World Economic Forum (WEF), some 88% consider job preparation to be the point of college. 39% are aiming for a career in medicine or healthcare, 20% in the natural sciences, 18% in biology or biotechnology, and 17% in business. A 2018 Gallup poll on over 32,000 university students randomly selected from 43 schools from across the United States found that just over half (53%) of them thought their chosen major would lead to gainful employment. STEM students expressed the highest confidence (62%) while those in the liberal arts were the least confident (40%). Just over one in three thought they would learn the skills and knowledge needed to become successful in the workplace. Because jobs (that matched what one studied) were so difficult to find in the few years following the Great Recession, the value of getting a liberal arts degree and studying the humanities at university came into question, their ability to develop a well-rounded and broad-minded individual notwithstanding. While the number of students majoring in the humanities have fallen significantly, those in science, technology, engineering, and mathematics, or STEM, have risen sharply. About a quarter of American university students failed to graduate within six years in the late 2010s and those who did faced diminishing wage premiums.
