I think kids are less hedonistic- I've worked in low income schools in Chicago for 15 years. Kids smoke less tobacco to the point where it is rarely seen, they drink way less beer, and less liquor, there are far fewer pregnancies, and I see far fewer used condoms laying around... for real... I think casual blowjobs are more common... they def smoke more weed though, although that is society as a whole... way more pills too... social media beefs are a thing... I dunno... I think I see more insularity and fewer groups of friends... maybe I just pay less attention...
