Many people take a while to figure out what career path to take. Not everyone knows what they want to do right out of high school. Sometimes, people who enroll in college don't finish their studies to get a degree. In fact, the dropout rate for undergraduate students is a whopping 40%. One of the biggest hurdles college students have that causes them to drop out is financial struggles. Some take on jobs as cashiers to help make ends meet and to have spending money.
