Mizrahi historian here:
There is actually evidence that the Hebrews made up a large majority of slaves within Ancient Egypt:
Ancient Egyptian art often depicts the Hebrews as being dirty and unclean, a state of peasantry or slavery. For the next hint at this, I will have a brief Egyptian art lesson:
In Ancient Egyptian art, red is seen as a masculine color, and white is seen as a feminine color. The god of foreigners, Set, had red as his primary color. Due to this, foreigners were also often painted red to represent foreign blood, while Egyptians could be any variety of colors. On to the point, the Hebrews were painted white. The men too. White, being the color of femininity, is used is this situation to denote the Hebrews as "Not Men", symbolically stating that they were not humans and thus the Egyptian rules of humanity did not apply to them. Because of this, the Egyptian religious code stating that "all men must be given their due" did not apply to them, and so they were not paid. Several other Egyptian religious laws, dictating the disuse of violent language towards others and the fair treatment of all peoples, as well did not apply. Thus, the Hebrews were given slave status.
There is actually something interesting about the Egyptian slavery though. According to several historical records, the Hebrews were paid with exotic fruits. While this technically does count as pay, since the Egyptians widely used a barter system along with currency, it was technically better pay than the average worker. This only furthers the distinction made between Hebrew workers and Egyptian workers.
To some aforementioned points, the Hebrews did not build the pyramids. The time at which the Hebrews were supposed to be in Egypt does not match up with the times that the pyramids were created. A fun fact, one of the most accepted theories to naming the infamous pharaoh of Exodus states that Ramesses II was the pharaoh. Which is funny, because that would mean that Ramesses was so grief-stricken from his firstborn's loss that he had 200+ other kids with 17 women.
