In exploring the systematic denigration of labor, the following is from Ali Khan, The Dignity of Manual Labor:

Aristotle considers leisure an indispensable precondition to living a life of virtue. However, leisure cannot be achieved without shunning physical labor altogether. Thus a life of virtue is neither recommended to, nor is it possible for, the slave child who, according to Aristotle, the gods create for no other purpose but to provide manual labor. This dialectical logic drives a wedge between leisure and labor, as well as between the elite and the manual child.

In the 19th century educational reformer, Horace Mann said,

The labor of the world has been performed by ignorant men, by classes doomed to ignorance from sire to son; by the bondmen and bondwomen of the Jews, by the helots of Sparta, by the captives who passed under the Roman yoke the villeins and serfs and slaves of more modern times.

In this statement, Horace Mann attempted to describe the sources of society's denigration of the work of the human hand.

One can see quite clearly that the divide between manual activity and the workings of the mind alone are clearly drawn in western culture, denying some the encouragement to discover the fulfillment of their own hands-on creativity and denying others the dignity that ought to be the just reward for the skills, wisdom and intelligence expressed through their hands. The divide is not one that arose as an accident, but was one of human intent as a means of deliberate subjugation.

It has been a couple days on the blog with no photos of kids at work, so I've added one below as remedy for the distorted view of Aristotle in which learning through the hands was to be carefully suppressed.
