A few years ago The Atlantic published this article by Joe Pinsker titled "Rich Kids Study English." It's a really fascinating piece that I hope you'll take the time to read, but here's the main idea: "the amount of money a college student’s parents make does correlate with what that person studies. Kids from lower-income families tend toward 'useful' majors, such as computer science, math, and physics. Those whose parents make more money flock to history, English, and performing arts." Hence the title. Pinsker looks at several explanations and unanswered questions about this connection with having wealthier parents and choosing lower-paying career paths. "It’s speculative," he says, "but richer students might be going on to take lower-paying jobs because they have the knowledge that their parents’ money will arrive eventually."
While the premise makes sense--if your family has more money and support then you can afford not to worry about paychecks as much when choosing your college classes--it's not the full picture.
