I graduated without debt, and I'm so glad that I did.
When I finished my first degree (in 1989) I had trouble finding a job. For about six months I worked office temp jobs during the day and waited tables at night, which was nerve-wracking because I every month I worried about making enough for my rent and my car payment -- forget lifestyle and extras. I had none. About six months after graduation I found a job, but it wasn't really a good one. If I'd been paying loans in addition to my living expenses at that point, I really don't know how I would've made ends meet. Well, yes, I do. If I'd been paying off loans at that point, I would've ended up going into credit card debt for living expenses, and it would've taken me a long time to get out of that hole.
When I finished my second degree (in 1991) I found a job within days, and things were much better. Of course, by that time, I was also married and my husband had been working while I was in school.
I am anti-loan. Usually other options exist -- they aren't necessarily your first choice, nor are they always convenient -- but most people who are young, healthy, and have no dependants can do something to at least minimize loans.
Here are the things I did to get through school without loans:
My parents weren't able to pay anything, and they actively blocked my financial aid -- the point being, I was on my own.
Living at home was not an option.
I chose an affordable college.
I was in college for five years with my first degree; however, I don't regret that choice. I couldn't have paid off a loan in one year, so I came out okay in the end.
I worked all the time. All the time. All the time. Usually I had two part-time jobs during the school year. I made Dean's List most semester and graduated with honors.
After my first two years, I became an RA. That was honestly my best money-saving job. It didn't pay cash, but I got a room for free, 1/2 my tuition paid, my telephone paid (not a cell phone -- didn't exist yet), and a couple other nicey-nices like priority registration.
I did two professional internships, which paid better than running a cash register (but not as well as waiting tables) and also beefed up my resume.
I lived frugally. I rarely ate out, rarely bought new clothing, always bought used textbooks and when possible shared them with friends.
