Other than that, I never had a job in college. Scholarships covered my tuition and my parents paid for my housing/food. I somehow came out as at least a somewhat successful human. Medical schools still accepted me, despite my lack of work experience.
Meanwhile, my roommate who pounded her chest over self supporting her entire education works in a dead end job for a rental company. Not to look down on that, but it's not like her working for all of college really landed her a great job. It tanked her GPA and she couldn't get into graduate school like she had planned. Her dad is an attorney and could have easily helped her out. I guess now he can be proud that he raised a self sufficient daughter or something.
My brother worked a few campus jobs in college. Minimal stuff (TA, Grader). He manages somehow to actually get a decently high paying job, despite the fact that he didn't pay for everything on his own. In fact, he was telling me just yesterday that there's a pretty strong divide between his friends who had help paying for college and his friends who didn't. I think he said that essentially every friend who paid their own way now works in some sort of menial job and every friend who had help paying for school went on to jobs that have higher pay and higher desirability.
