Why are civil servants important to society even though they often work in the background?

Civil servants are vital to society as they ensure essential government functions operate smoothly but often go unnoticed. As described in the clip, they form a 'background app' that silently maintains critical systems - preventing planes from crashing into each other and ensuring checks arrive on time. The effectiveness of these public servants has paradoxically made their contributions invisible; the system works so well that citizens rarely recognize the role civil servants play in maintaining public safety and reliable services. Their behind-the-scenes work forms the foundation that allows society to function properly, highlighting why their value needs to be better understood and appreciated by Americans.
