It’s not just that. I specifically said tradesmen as workers villages had lots of amenities for the workers. The whole idea of the pyramids themselves not involving slave labor is based upon a tomb that was found near the workers village. It’s is understood that it was the tomb for the workers, and it was a bit more elaborate than just a mass grave for slaves. 

Of course, it is assumed that Egypt was ruled by an absolute monarch, so the distinction between what it means to be a slave as opposed to a worker within that kind of system is blurred.
