> Kids don’t even play outside anymore and I don’t think it’s because the market took away third spaces
I agree with this, but I think it reinforces GP's point that what's missing is time: slack in the day. I grew up playing outside with all the neighborhood kids, and the critical enabler was that there were always adults around during the after-school hours. Not actively hanging out with us, or even closely supervising, but around. Some of them (mine, but only for a few years), were stay-at-home mothers, but by no means all. One family had a dad who got home early from work. Another kid we couldn't play at their house certain days, but we could others, because their parents had variable schedules.
There were also more kids around, because families back then had more kids than they do nowadays. I think that's also (not entirely, but to a significant degree) a consequence of adults having less time - across their life-cycles, and in their days - that isn't devoted to work.
No ones' parents did gig-work, or worked two jobs. Most parents were 9-5, or maybe 8-4 (or I don't know: I was a kid, and not paying attention to things like that), but no one went to "after school care", because there were always adults around after school got out.
Hell, I think the need for third-places (for kids) mentioned in the article is a down-stream effect of the increased time pressures on adults' lives - as is the disappearance of third-places for adults.
I don’t know if I can come to that conclusion. Certainly there some grain of a truth there but even when the parents are home kids are not out exploring. At least in America there is an obsession for experience maxing with kids. I don’t know if it’s a time problem or a shift in attitudes.
You're right about there being a change of attitude, particularly in the direction of mis-perceived risk - we see that in surveys about fear of crime relative to actual crime statistics - which makes parents way more leery about sending their kids outside to play on their own.
I think that's a huge mistake: there are child-development studies that suggest that it's important for kids to engage in (moderately) risk-taking play in order to develop accurate assessments of their own skills and calibrate their own internal risk models; other studies suggest that it's helpful for children's social development to spend time playing independently (of adults) in age-diverse groups of other kids. My opinion is that the parents who (e.g.) follow their kids around the playground, making sure they don't fall down and settling every squabble, are not being helpful - though not doing that sure got me dirty looks from other parents!
So, that's where at least some of the "kids aren't exploring outside" effect comes from. My own (GenX / "latchkey" / elder-millennial) cohort was arguably under-patented; now we ourselves have over-corrected with our kids. Maaaybe the idea that at-home entertainment is today more compelling or convenient has something to do with it, but I don't know: my generation was plenty compelled by TV and 8-bit Nintendo. I think we'd have spent just as much time on those as kids today spend on whatever they do on their devices now.
However, I think the primary drivers are:
1.) Fewer kids around, both per-capita and (related, but separable) per geographical area: you can't have a spontaneous neighborhood "gang" when other kids don't live nearby. Declining birth rates and increased sprawl force parents to be more involved in their kids' social lives, as transportation to / organizers of scheduled activities and formalized "play-dates". (Of course, this only increases the time-pressure on parents, and makes it even more difficult to imagine having more kids. It's a vicious cycle.)
2.) As you say, experience-maxxing. Some of this is great: parents in general seem to be way more (emotionally healthily!) involved in their kids lives than my parents' generation ever were.
(But one example: I think my parents might have attended one or two of my Little League or high school baseball games, ever. It didn't hurt my feelings at all: parents mostly didn't, and we kids mostly thought the families who came every time were kinda weird, and were a bit embarrassed for the teammates whose parents showed up. Today, I love how much support my kid and his peers receive at their games. It's fantastic. [Coming to watch practice though? Nah. That's a little too helicoptery. Parents, don't do that, unless you're volunteering to help coach the team.])
On the other hand, I think a lot of the other efforts parents make - structuring every afternoon and family weekend around doing something kid-friendly - isn't such a good thing: kids need a little boredom and a bit of independence to spark their creativity. But... For time-pressed parents, who genuinely and rightly crave interaction with their kids, those hours are precious: that's all the time you get, so the temptation to over-schedule is strong.
I think both of those factors reduce down (in large part) to time pressure. Having to work or train longer, and on top of that having to have more than one income, to be financially stable increases the (fractional) time investment, and then all of it compounds.
It's not a simple answer, but I think higher wages, better social and societal support for families, and denser built environments would all help to pull societies away from the current equilibrium. Developed countries are all well below replacement birth rates, while at the same time surveys indicate that most women have fewer children than they'd "ideally" want. There's something off kilter in the way we're living our lives, and I think it's downstream of the economic system we've collectively built.
(Sorry to hit you with these walls of text. I've spent a lot of time thinking about this since becoming a parent.)
