In a perfect university teaching environment, yes. However, in real life sometimes cheating is necessary. Real university environments are flawed, rules and requirements often stacked against the student. They have to pay up, get a massive loan, endure narcis/dumb teachers and stupid administratory requirements, and educate themselves despite that environment. After a lot of invested time and money donated by state/parents, if faced with particularly nasty course exam they are unable to pass in a legal way, it would be crazy to fold and waste all that investment.
