You only say this because you have never held an administrative position or undertaken major service.
In the meantime, I will remove the services of your IT department and those in charge of your physical plant. If you are foreign language faculty, I will remove the study abroad office from your university while also requiring that you further internationalize your campus. This is just to start; more support will be removed after you get used to these things.
We will see whether, after that, you still say administration is useless and service is easy.
