Why does the labor content in services complicate efforts to improve productivity?

Because a high labor content implies that services can be easily automated, making productivity improvements unnecessary.

High labor content limits the scalability of productivity improvements due to the inherent limitations of human performance.

The presence of high labor content indicates that most services are provided at a fixed location, simplifying productivity improvements.

Services with high labor content are less likely to require customization, making it easier to improve productivity through standardization.
