Going to college is a serious investment. Over 44 million Americans collectively hold nearly $1.5 trillion in student debt because they know that earning a college degree is crucial to get ahead in the modern economy.

According to the Georgetown Center for Education and the Workforce, early childhood education majors report median earnings of $36,000 a year while petroleum engineering majors see median earnings closer to $120,000.
