The answer is "True" - Bryon does state that it is difficult to tell a greaser from a Soc anymore.
Where Bryon lives in Oklahoma, the kids from the "real crummy part of town" are the greasers, and those from the "pretty ritzy part of town" are the Socs. In the past, the two groups would distinguish themselves from each other by their appearance - in the way they dressed and how they wore their hair, and they would frequently face off in violent brawls. With the advent of the 1960s, however, a time characterized by hippies and a professed attitude of "all that love, peace, and groovy stuff", the fights between the two groups "slacked off", and members of the groups even started to look alike. Bryon says,
"...it was hard now to tell a Soc from a greaser. Now the greasers wore their hair down on their foreheads instead of combed back...and the Socs were trying to look poor. They wore old jeans and shirts with the shirttails out, just like the greasers always had to because they couldn't afford anything else".
Bryon goes on to note that in many ways, the apparent blurring of divisions between the richer and poorer classes as exemplified by the Socs and the greasers only went so far as the surface. He observes that
"...what with fringed leather vests and Levi's with classy-store labels in them, (the Socs) were spending as much money to look poor as they used to to look rich...it was crazy".
He further observes that although the guys that used to be called Socs made great efforts to include smart greasers like himself in their lives, sometimes it seemed that they did it just to show how "liberal" they were. They really didn't care to know whom Bryon was as a person at all (Chapter 4).
