Explain why things are "rough all over" from the Outsiders.

That line is spoken by Cherry in chapter 2.  Ponyboy Curtis has just narrated the past events about Johnny's beating and brush with death.  He told Cherry, so that she could understand why Johnny looks so hurt and scarred.  Cherry expresses her sympathy, but she does not cave and tell Pony that the Greasers have it way worse than the Socs.  She tells Pony that "things are rough all over."  Ponyboy, to his credit, believes her.  Eventually, the reader learns exactly what Cherry was talking about.  The Socs have it equally as rough as the Greasers.  It's just different.  The main problem with the Socs is that they are hollow and emotionless.  They rumble and fight just to feel something, anything.  At the crux of it is the fact that the Socs are every bit the rebellious teenagers that the Greasers are.  They are all trying to fit in some way and not disappoint each other or their families.
