What does Cherry say is the big difference between the Socs and Greasers?

In Chapter Three, Cherry assures Ponyboy that Socs have troubles of their own and that "Things are rough all over." Ponyboy sees money as the biggest difference between the Socs and the Greasers, but Cherry tells him that money is only a part of it. She says that Greasers are "more emotional", whereas the Socs, pride themselves on their "aloofness" and being "super-cool." Cherry says, "We're so sophisticated--cool to the point of not feeling anything. Nothing is real for us."
