Why productivity tends to be lower in the service sector that in the manufacturing sector?

Productivity in the service sector often tends to be lower than in the manufacturing sector due to the nature of service delivery, which typically involves more human interaction and less automation. Services are often intangible and can vary greatly in quality, making standardization and efficiency more challenging. Additionally, many service jobs are labor-intensive and require significant time investment per customer, while manufacturing can leverage machinery and technology to produce goods more efficiently. These factors contribute to the overall lower productivity levels observed in the service sector.
