Things like universities and colleges are post-secondary school. You are getting the more skill. This is like an invesment, which makes you get more thing back from the society. Education fee is reasonable.
And the public middle school and high school should be free to everyone. This is goverment's duty.
By the way, someone here has ever mentioned about the education fee in U.S. is not high. I think you'd better to know exactly. You can just go to the web-site of UC and see their tution for native, which is the lowest in U.S.
Anyway, edcation itself is a special industry.
