A reason given by the state for the hike in university fees is that is not cheap to provide quality education. The education sector is perhaps the slowest industry to adapt to changes/advances. With the internet the cost of delivering top notch education by experts around the world (which you can choose) has shrunk a great deal.
Instances of people sharing their expertise/advice is not uncommon on the internet.
Telling people that quality education doesn't come cheap is just to fool people into continuing paying exorbitant fees. Ratio in S'pore primary & secondary schools still range from 30-40 pupils to 1 teacher - doesn't like spending a lot.
