What does Cherry help Ponyboy realize about Socs and Greasers?

I think the end result of Cherry's lessons to Ponyboy is that Ponyboy realizes that the Greasers and Socs are a lot more similar to each other than they are different from each other. We see this really clearly when Randy is leaving Ponyboy's house, and Two-Bit makes a Soc crack about Randy.

"What'd he want?" Two-Bit asked. "What'd Mr. Super-Soc have to say?"
"He ain't a Soc," I said, "he's just a guy. He just wanted to talk."

Instead of laughing at Two-Bit's little jab, Ponyboy essentially defends Randy. Ponyboy doesn't label Randy as anything other than just another guy like all the rest of them. By this point in the story, Ponyboy has really come to learn exactly what Cherry meant when she told him that things were "rough all over." Cherry explained to Ponyboy that life wasn't slick, clean, and easy for a Soc either. They have problems too. The problems might be different, but those problems still cause just as much mental and emotional trouble regardless of whether or not the person is a Greaser or a Soc.

Cherry Valance is a Soc cheerleader, who meets Ponyboy and Johnny at the drive-in movie theater after Dally begins to annoy them. Initially, Ponyboy is surprised at Cherry's tolerant, friendly demeanor and even shares with her the story about Johnny's traumatic experience when five Socs jumped him. When Cherry tells Ponyboy that all Socs are not stuck-up, callous individuals who enjoy jumping Greasers, Pony responds by saying "Sure." Cherry then proceeds to tell Ponyboy that he would be wrong for thinking that all Socs have it made and mentions that Ponyboy should not believe that their lives are perfect. Cherry goes on to teach Ponyboy a lesson on perspective by telling him that Socs have numerous issues. Cherry then tells Ponyboy, "Things are rough all over" (Hinton, 31). Overall, Cherry Valance humanizes the members of the Soc gang and helps Ponyboy view them in a different light. After speaking to Cherry, Pony learns that Socs also have issues and struggle in different areas of life.
