It's expensive enough anyway compared to many other EU countries where universities are essentially free.
There seems to be two systems of University Education
1) A system where university places are very restricted and only the very best students can attend. This allows the state to fund these places completely.
2) A system where if a student reaches a minimum entry requirement a university place will be provided. These places are in the main funded by the student.
The UK has moved from System 1 to System 2. In 1960 the UK had 22 universities and only 4% of students went to university.* Currently the UK has 133 universities and more than 40% of students attend.
I make no comment on the merits of either system.
It would be interesting to look at the 27 EU countries, and Greece in particular, for comparison. Perhaps some have found a "third way"
*In addition to the universities there were Technical Colleges where students attended part time whilst working and Polytechnics.
