When the leaders of a country are insulated from the problems they are elected to solve, solving those problems is quite difficult. the children of many national leaders attend private schools. what would those leaders know about today's public education?

Very little, but not, however, as little as one might think. the vast majority of the world leaders are dedicated, while growing up, being privately educated, however, they are simultaneously introduced to a wide and vast array of different languages and cultures, as well as geographical locations, etc. So, therefore, it is entirely posse that a national leader may, in fact, know about average, or perhaps they know just as much, if not more, pertaining to the public education system as well as the public schools themselves. It is entirely possible that they may, in fact, know just as much as those children who are expected to attend those institutions. I suppose it depends upon the person, and what type of background the national leader comes from.
