That is a vision, and not only that, but some countries have even gone so far as to say to those families of modest and low income that if the students, never mind the tuition, cannot even afford to leave home to go to the institution they qualify for, the countries will provide a grant.
A grant is free money. Do members remember the 1960s and 1970s when we went to university? We used to get grants.
Countries in Europe are saying that they will provide a grant for families of modest and low income so that they can provide for the food and the housing needed while the students get their education. Then they do not have to worry about that.
