"The boys and girls come from the poorest classes, from families in which the mother has died, and, in about 80 percent of the cases, in which the father has abandoned the children. Considering these conditions, one would expect a great many behavioral difficulties- either destructiveness or sexual problems... But contrary to such expectations, no major behavior problems exist among these children. There are practically no problems of violence in the sense of serious physical assault against either another member of the community, teachers, outsiders, nor are there any serious sexual problems...What is remarkable, however, is the absence of not only major behavioral problems but the presence of a spirit of cooperation and mutual responsibility. The boys and girls feel themselves to be members of the “family” and are proud of this membership, although this family is not based on the common tie of blood and is so large that it exceeds the limits of what could even be called an extended family. It is actually a community with life centered values, characterized by a spirit of cooperation and responsibility." 〔Erich Fromm, Michael MacCoby (1996). ''Social Character in a Mexican Village''.
