Why where they so much more skilled than today's schoolchildren?

Imagine training a chihuahua to do tricks, then looking at an untrained golden retriever, not even try to teach them, and saying “why are chihuahuas so much smarter than golden retrievers?”
A perfectly legitimate answer to that question might be that we stopped teaching them.
Of course modern writing/drawing utensils are on an entirely different level and paper was very expensive back then e.g. an average labourer supposedly only made enough per day to purchase less than 100 sheets, so practising was expensive.
