Why is it necessary to take college courses that have nothing to do with your major?

This is a question from a friend of mine, and I decided to ask it here because I didn’t really have an answer.

”... [ the college system ] _ is mostly based on how it is a profit oriented education system, which is ridiculous. They force students to take additional courses and programs that are not at all related to their focused career path or course of study and pay for it. Let alone other classes and courses. I mean, literature and english classes make sense, for helping people actually communicate their ideas, sure.
But beyond that, it’s still a system designed to maximize profits, and it doesn’t even guarantee a job or success to put oneself into massive debt_.”

So? What do you guys think?
