The overwhelming majority of supply chains are productive, there is no value without labor and/or natural resources. Overproduction is an inherent fact of capitalism, and reducing laborers both reduces surplus value extraction and reduces the potential for profit by reducing the number of customers. Capitalism brutally killing off the reserve army of labor is a way to keep workers desparate and willing to work for as little as possible, it isn’t a way to curb overproduction.
