Pony boy has a more realistic view.
1 reason is all the socs care about is how they look pony boy even says.
“even if they did have their own troubles, I really couldn’t see what socs would have sweat about- good grades, good cars, good girls, madras and Mustangs and Corvairs- Man if I had worries like that I’d consider myself lucky. See the socs have all the good things and don’t have to even work for anything.
Another reason is the greaser will never win against the socs pony boy says.
“Dally had no specific thing to hate only socs and you cant win against them no matter how hard you try, even whipping them isn’t going to change that fact maybe that was why Dallas was so bitter. 
See even if you try your hardest you cant win against the socs. 
Some may argue that Cherry has a more realistic view but all she is saying is that the socs have harder troubles then the greasers. 
However pony boy has lost both his parents and some of the greasers parents abuse them that’s why some of them live on the streets.
