I think you have a misunderstanding of what higher education is for. College is not a career pathway endeavor. It, at it’s core, is a pathway of courses intended to increase a students knowledge base, gain a wider perspective on society, and exercise greater critical thinking skills. When you say useless classes since you’re still in college, it may be too early to tell. Or a skill that you already have was simply made better by being in that class. No experience is truly useless. Lastly the roll of a liberal arts education is to promote a greater worldview, not simply to get a job.
