Of course the stupid part is - there are strong indications that the pyramids were NOT built by slaves - Jewish or otherwise.
they date from well before the Semitic presence in Egypt.
And the tombs of pyramid builders nearby indicate they were farmers in the agricultural off-season working on a communal project and getting paid (in grain and otherwise) for it
Of course those who worked on it were fed and housed for the 20 years of construction. But it was a hierarchical society, effectively, yes of course they were slaves. There's a modern political imperative that has nothing to do with anything but nationalist politics in Egypt and an ass-kissing need for those who want to work in Egypt. No need to buy into the fiction.
