Looks like a pyramid scheme to me.
LOL, but yes, the Pyramids do look to have been a Pyramid scheme.
The Pharoah got his ‘resurrection machine’ built for him (no mere tomb but a way to the next life).
And the laborers not only ate very well for people in the ancient world, but when they died they were buried in choice locations near the Pyramid so that they could join in the Pharoah’s eternal life.
