„In OECD member states, most of the funding for educational institutions, from primary to tertiary level, comes from public sources, with significant private funding also being involved at tertiary level. […] At tertiary level, due to the high returns of tertiary education for private individuals, some countries require these individuals to bear a greater financial burden through tuition fees.“
