The social model examines how society contributes to a person's health and well-being, taking into account factors such as education and environment ; “Healthy people are those who live in healthy homes and eat a healthy diet in an environment equally conducive to birth, growth, labor, healing and death…” (Illich, 1976) . The social model has many advantages, for example; Education is considered a major factor in disease prevention and health promotion. Marx (1818) believed that the level of education and care you receive depends on your class. If you are rich and upper class (the bourgeoisies), you are more likely to have a higher level of education and better health care, but if you are working class and lower class (the proletariat), you are less likely to have access to good education and better health care. A disadvantage of the social model is that it is not possible to prevent all diseases. Breast cancer is an example of a disease that cannot be prevented by any form of socialization, but thanks to advances in medicine, cancer patients can now live longer and lead more normal lives.
