It's just that this kind of international comparison is not trivial. To take an obvious example, South Korea boasts of a 20 % of GDP "education budget" - but they include primary and secondary schools in that figure!

Similarly, if less blatant, at anything below postgraduate level, there are structural and organisational differences between Europe and the US that make comparisons a non-trivial exercise.
