Are you speaking from experience or perception?The 9th graders themselves are different, because their entire world has been different from the get go. It's seriously incomparable. They are jaded as hell by the time they get to the 9th grade, because literally every adult in their life has failed them. And you know who are the ones who "give a shit" to them early on? It's the drug dealers. Like when the drug dealer comes by and pays for all their school clothing. We are products of the environment we grow up in.
Also i just get fed up with that at least the way the show presents it. Break free from your environment or change it. Don't accept the tricks of the drug dealers and always give the people who are trying to help a chance. Understand that they're trying to keep their job too. You gotta start the good will on one side or the other and if the adults don't seem to be doing it unfortunately it's up to the kids sometimes
