Similar generations and i've noticed the same thing, but living in an urban place, in a large complex of socialist apartment buildings, in a country that fell apart from a larger socialist one to a smaller capitalist one.
Two of the biggest differences were extracurricular activities and technology... back in my day, you maybe had one or two 'after school' things per week, usually immediately after school, for an hour (so you'd end at two oclock instead an hour earlier) and you then went home, where you had one tv per family. When your parents came home, the tv was gone, dads football, moms series, evening drama movies... and what were you supposed to do then? Read? Well.. you went out. ...same as most of your friends. We sat on benches, played football, basketball, girls wanted attention, got attention, from young-kids age to the age of neighbors caling police due to 'loud teenagers' outside.
And now? Every parent with kids has their kids in one additional language course, some music classes, sports, and not like once a week for an hour or two, but two, three times per week each, at different locations (=driving them around, even though there are a lot of busses). The kids are physically tired from all that, and then they get home, don't even have time to get bored, and even if they did, they now have a tv, phone, computer and a gaming console right in their room. Their friends aren't outside either, since they're being chauffered around for their activities. No proper socialization with peers, no time to do stupid stuff, no time to be bored... nothing.
And it's not even worth it... none of those kids will be a professional sportis/musician, it's just wasted time... yes, excercise, but we exercised too, by being outside, walking, biking, playing footbal with stones, etc.
tldr: blame parents
