Manufacturing involves using machines, tools, and labor to produce goods for use or sale. It includes a wide range of consumer goods like textiles, chemicals, and engineering products. Manufacturing is considered a secondary industry and describes the production process in factories and industrial plants. While modern manufacturing tools driven by computers have advanced production, they have also led to increased unemployment as human labor is replaced. Manufacturing provides revenue to governments and benefits communities by creating jobs and satisfying customers. It can take place under different economic systems but typically aims to mass produce goods for profit under free markets or state planning in collectivist systems.
