College tuition costs should be lowered because, more people would be able to attend, attending college benefits society not just the students, and it is a good investment for peopleâs tax dollars.
Universities Are Rightâand Within Their Rightsâto Crack Down on Speech and Behavior. Students today are more like children than adults and need protection. By Eric Posner. College students are still children. Not in terms of age, but in terms of maturity. Even in college, they must be protected like children while being prepared to be adults. There is a popular, romantic notion that students receive their university education through free and open debate about the issues of the day. Nothing could be farther from the truth. Students who enter college know hardly anything at allâthatâs why they need an education. Classroom teachers know students wonât learn anything if they blab on about their opinions. Teachers are dictators who carefully control what students say to one another.
