In general parents are much more hands-on spending time with kids than used to be.
And then all these prep schools are pushing these heavy workloads & mandatory "extracurriculars" to force the kid to be well-rounded. No time to read "Fear & Loathing in Las Vegas" or go get stoned/laid, or just chill at the mall/record store/lake...

But then for many special needs, navigating the traps of the 1-size-fits-all school system designed to weed out any marginal performers/square pegs before college can be quite harrowing.

There are some advantages to helping kids into internships & careers - it's not like that's not the expected benefit of the first couple years in the workworld, to start learning the ropes, and if they do acquire the needed skills to do online marketing, Youtube self-promotion, whatever - yeah, it's a sustainable business practice that can fund a whole lot of leisure or other opportunities. Even if the parents do everything at first. Though if it's just parents keeping a hand in everything, it's more an extended family franchise, as seen so well with the Kardashians. (Kiley's billion dollars owed primarily to her mother's expert marketing skills & promotion, even if she contriubutes something - she's still the product, Kris Jenner's the creative genius). In general, pushing some practical activities but putting more and more responsibility on the kid is roughly a family internship - not bad.

Sure, if you're the by-the-bootstraps self-motivated 17-year-old, this probalby won't be necessary. But as parents we're also worried about what happens when the robots come, most basic work is offshored to Asia, and all that's left are wiping-peoples-butts-for-$7/hour jobs, yeah, economic anxiety.
