When we build houses with our hands, we cannot afford to think about calculus. Perhaps somewhere down the line, somebody did, but we are using our hands. We need to focus on the bricks, and the spirit level. People's lives are at risk if we do not do our job properly. So it makes sense that a brick layer's household will be devoid of calculus. Imagine a generation of brick layers. Imagine the lack of calculus here, and now try teaching calculus to the child of this family. The parents can't help, they may have even learned to scorn any such thoughts, as to protect their interests at work, and so this child will be between a rock and a hard place. If they choose, they can go and find out for themselves independent of family, but the chances are they've already been brought up around enough conversations about how difficult and pointless advanced mathematics are, they don't have the drive. It's perfectly reasonable to see this situation manifesting.
So bearing this in mind, when presenting children with an education suitable for their needs, we must address the culture of their upbringing. In schools that have pupils from every walk of life, then the institution has to offer a responsible array of varied subjects that appeal to all. And when considering which angle to address when educating a child in the application of the education, the culture is also an important factor. Academic skills are the backbone to manual ones, as without them, we would not have the tools or the knowledge to achieve such things. If we tell a child that this lesson helps with learning how to build a house, and then teach them angles, physics, algebra and geology, the statement remains true and it also inspires them. If we tell them that it's just a part of the syllabus and to do their best, they probably wont.
