The TV show How Its Made highlights how everyday items from toothpicks to robotic arms are created and assembled from beginning to end. Does this prove how capital is heterogeneous?
No it doesn’t. Each of these processes requires the addition of time, labor, and previously produced physical goods (capital). For example the creation or assemblage of toothpicks or robotic arms might be highlighted, but what about the machines used to produce these goods and the efforts required to assemble the labor force involved? These must exist before the good can be produced.
