Think about that for a moment...
Slaves were property and as such valuable in their own right. Then, add in the Pyramids at Giza are not simple piles of stone, but very sophisticated both in their construction and in design.
They were not built by a people who did not care, nor by a people who thought nothing of the deaths of highly skilled workers.
Finds near the pyramids at Giza prove that the workers were highly valued and well fed. No whips involved.

Further, there is no existing evidence which proves conclusively that the pyramids were not preexisting and later rebuilt during the reign of Khufu and sons.

Hawass is a womanizing clown whose intellect soars past the obvious and into the stratosphere of Egyptian and Islamic nationalism.
The Kufu legend is a scam perpetrated by an archeologist determined to find something. He forged the supposed writing on the stones inside the great pyramid just like he forged other “finds” in the past. The pyramids were already there when Kufu reigned as evidenced by a stele found near Giza that had a depiction of the pyramids.
