How fair did the Egyptians consider the obligation to work on the construction of the pyramid?

We can say that they considered it their duty to build a pyramid-tomb for their ruler. After all, the entire Egyptian people were considered the servant of their pharaoh. Such construction often involved tens of thousands of workers who have worked in construction for many years. So over a thousand years, the ancient Egyptian pharaohs built hundreds of tombs for themselves, which amaze with their scale and scope.
