I think it is interesting to that magical education largely fails to teach students the most basic, practical spells that would be useful in everyday life; a failing shared by the muggle primary education system. It has become a common 'meme' in our non-magical world that students are reliably taught that "The Mitochondria is the Powerhouse of the Cell" but do not know how to do their taxes or balance a checkbook. I think that JK is on point with this parallel in the magical primary education system.
