The central idea is that ancient Egyptians had diverse burial practices that varied based on social and economic status, impacting the mummification process and funeral ceremonies.
Supporting evidence for this includes the mention that people with little money used used clothing to pay for embalming services, while those with more wealth had access to more elaborate mummification processes, including the use of perfumes and more extensive care for the body. Additionally, the mention of wooden coffins illustrates the different levels of expenditure related to funerals in ancient Egyptian society.
