Human-made resources, also known as capital or capital resources, is material wealth created by humans that can be used to create more wealth. Examples include money, factories, roads, and technology. natural resources are raw materials and land.
human resources are entrepreneurs and labor.
man made resources are refined raw materials that need additional value added work to become finished goods, such as raw steel, aluminum, and other commodities that are not simply taken directly out of the ground.
some might argue that capital is also a man made resource; being the plant and equipment used in the production process.
by adding capital to the equation, we have an explanation of all three scarce economic resources: land, labor and capital.
