You have no right to a formal college education.
There I said it. Bring out the pitchforks. Its a hot topic in CA nowadays for student to demand the state continue paying much of their formal education. They're wrong. The state of CA made sure they got to adulthood reasonably educated and with life habits that come from school work. Now its their choice on how to grow them (or not).
You have a human right to information for self study.
Most likely this is via the internet. Maybe the books at the library. Maybe you work a job where you can hear another language or you post pictures for feedback on a website. Maybe you learn programming from a website or history from a old textbook. You do NOT need a professor to learn. You do not have a RIGHT to be taught by a professor. Your high school teachers did not teach you so you continue to rely on others, they taught to to be an effective human so start applying those skills.
I go to a private university because it is more efficient and enjoyable to learn in a formal environment (particularly that of my chosen school). I am majoring in Japanese studies and would like to do a 3-2 MBA program. My parents and I feel that the private formal environment is more efficient and enjoyable and that it is worth the cost. State students ought pay because they feel the formal environment is better for them than self study but they do not want to pay for the differences of a private school.
ALL students can self study if they do not feel their education is worth paying others for or if they can't pay/don't want loans. I started studying Japanese in middle school or early high school (don't remember) by buying a 10$ kana book and using David Hallgren's Japanese page. After a while of this when I began moving on to kanji, my parents decided to send me to a private Saturday class in Japanese. I got up at 7:30 every Saturday for years to go to a 4 hour class in Japanese language and culture. I love that school, I am grateful for them. While they didn't push students very hard, a motivated student could learn quite a lot and I passed JLPT 4-kyu last December (took it on a whim). I placed into Japanese 331 for freshman college and took JLPT 3-kyu this year. I won't say the formal education didn't help me (it did) but the motivation that made this happen can be applied to self-study.
Only you can better yourself. If you don't like the system, stop relying on it and study on your own.
