„Financial resources are one of the cardinal enablers of quality learning environments. The extent to which a country invests in education directly impacts not only its citizens – affecting student enrolment, student school life and teachers‘ working conditions – but it can also profoundly enhance the productivity of a society, leading to long-term economic and social benefits.“
