How we cite our quotes: (Part.Paragraph)
Quote #1
I'm not sure how you spell it, but [Socs] is the abbreviation for Socials, the West-side rich kids. It's like the term greaser that's used to class all us boys on the East Side. (1.4)
Money seems to be the main thing that divides the Greaser from the Socials, at least from Ponyboy's perspective. He sees his society, and maybe the world, as divided by those who have and those who don't. Do you agree with him?
Quote #2
We're poorer than the Socs and the middle class. (1.5)
Basically Pony is saying that he and the Greasers are the lowest income group in the city.
Quote #3
No rival gangs, only Socs. And you can't win against them no matter how hard you try, because they've got all the breaks and even whipping them isn't going to change that fact. (1.47)
At this point in the narrative, Ponyboy seems to believe that socioeconomic status is the deciding factor in every situation.
