However look at the tuition for any school now - even working full time there's no way it would be possible to escape any modern college without significant debt.
Actually it is possible, and people do it all the time. Some earn scholarships, use AP credit from HS, have help from parents, or just work hard. I worked 25-30 hrs/week with a 3/4 course load and full time in summer with a 1/4 course load, tuition was $2000/semester so I paid $5k/yr, rent was $2500/yr. I worked full time during christmas break and other school breaks, bought textbooks online, rode a bicycle (w/ snow goggles in winter), no grants, minimal scholarship money, no debt. With no car and no cell phone, and by not living on campus, you can save a lot of money. If you find yourself short on cash, take less classes that semester, and take more hours at work.
