To be fair, the current consensus is that slaves didn't build the pyramids, and that they were paid contractors (which I suppose makes sense given the required skills for a pyramid and the total cost)..
AFRICAN EGYTPIANS ENSLAVED WHITE PEOPLE AND FORCED THEM TO BUILD PYRAMIDS; AND THE ANCESTORS OF THE ENSLAVERS ARE DEMANDING MONEY FROM THE ENSLAVED FOR SLAVERY?.... BUT THAT'S NONE OF MY BUSINESS
