I’m not sure I go along with “infantilizing,” but I do think there are some respects in which parents of older teens/young adults delay their kids’ assumption of adult responsibilities.
I have long decried society’s belief that kids should not be allowed to walk anywhere beyond the end of their block for fear they will get hit by a bus or snatched by a perv. Just recently my wife and I were talking about when our youngest daughter insisted that we let her walk home from kindergarten (maybe 4 blocks, no busy streets) alone. And it would piss us off when he had our kids walk to their friends’ houses, and then the other parent would drive our kid home because they thought walking was not safe/responsible.
But I see some weird dynamics taking place. The “dressing like hookers” meme is consistent with the fact that at a very young age kids are bombarded by “mature” influences. Style, music, movies, vidgames, internet… One of the most common issues many parents have is what type of movies to let their kids watch at what age. And - whether true or not - parents hear of ever-dropping ages for sex, drug use, smoking, drinking, etc.
But this is not the same as to say kids “mature” or take on responsibility earlier. It seems to me that kids’ activities are directed by their parents more than when I was young. One example is sports leagues and such other than pick-up games. With a league, parents do the scheduling, enforce rules, resolve disputes, etc. Kids learn a heck of a lot by having to do that kind of thing themselves.
Personally, we sensed that our kids were not in a great hurry to “grow up.” So we were willing to shield them from somesuch influences, to allow them to enjoy being kids and playing and imagining longer than some of their peers. We always assumed that their maturing would be an inevitability, and that by the time they reached their late teens they would naturally mature in response to societal influences.
But we’ve been surprised that that hasn’t been the case. I think that a lot of the societal influences that appear “too mature” for young kids, don’t really convey the responsibility and ethics I find desireable in adults. So we have found ourselves in the position of sorta seeking out situations and opportunities for the kids to gain experience. They all had to get jobs when they were 16. They had to establish their own bank accounts, etc. Of course they had chores, and their main job was to excel in school. And we didn’t just give them cellphones, complete free access to the car, etc.
We find ourselves vastly in the minority, however. Many kids attain college age with very little experience as to what things cost, and the implications of their actions. Little distinction between earned privileges and luxuries, as opposed to necessities. A datapoint - my wife teaches business law in a community college. One section deals with contracts. She has been unable to identify any area in which she can assume her students all have experience with contracts. The majority of them live at home, so they never paid rent or utilities. They all have cellphones/internet - paid for by mommy and daddy. They are carried on their mom and dad’s insurance.
One reason we encourage our kids to go a way to college, is that at a distance they need to become more independent - even if they start in the supportive dorm situation.
So, I think it is a little more complex than the OP suggests, but I think there is something to what she suggests.
As far as “proof” re: this generation, I don’t have it but would look for it in terms of percentage of high-schoolers who worked, age at which people held full-time jobs, established bank accounts, bought their own cars, moved out of the house, extent to which kids contributed to the cost of their education, etc.
