1) it is trying to depict the difference between poor, run down schools in intercity areas and the beautiful nice clean (rich) schools in suburban areas.
2) the cartoon references the white flight movement because white people moved out of urban areas and moved into suburban areas. the title comments on the image by saying one nation but to many of the inner city schools and its pupils that statement may be incorrect because to them it had become two nation and dived into urban and suburban.
3) the suburban schools may have affected the inner city schools by making the schools shut down because of lack of kids since many of the kids parents were moving to the suburban areas.
4) some other aspects that affected the life in urban areas was that many of the people lived in slums and they lived in run down places plus there was a lot of gun violence. ( I'm guessing on this one sorry but if i come up with a different answer for #4 i will let u know.)
