IMVHO there are various variables the article do not take into account: we are in a decadent society, decadent enough that most cohorts/social classes see it, but in a too early stage to see something new to start structuring enough to know what we can do to pass the mess.
Middle class is deeply demolished, pushed to far lower level of wealth, high, but not so high class start seeing a possible escape toward a new neofeudal class but present situation is too liquid to been able to spot a right place and development plan, the only reasonable target is being flexible and diverse as much as possible, and that for young of the first cohort means the certainty of a future worse than that of their parents, witch fuel unrest and abandonment not taking careers since so far no one taught as you want seems to appear. For the second cohort that means try avoiding a career at all to avoid being trapped preferring gambling on family money waiting for the appearance of a more defined future. Both those cohort are acculturated enough to know that in anything the first pioneers who arrive, the frontier/first line will suffer and die quickly, the seconds, thanks to the knowledge of the pioneers prosper and the third will arrive late to prosper.
Poor know that they will be poorer but that is sold as not a such bad thing, they say society keep going in the end, humans are there for millennia and while there was good and bad moments for the real poor situations have mostly improved a bit, having seen a potential "in 2030 you'll own nothing and be happy" many of that cohort trust or at least desperately hope that that's will be the case.
So IMO essentially all "social classes" except for a very thin and more and more thinner élite see a bad future and no interest to do anything positive, some because there is no logic possible plan to go through the storm some because they think the storm is already around them and they can just hope not knowing because of lack of culture the classic una salus victis nullam sperare salutem.
Honestly, myself, coming from a wealthy family who can afford essentially anything we might reasonably want having a good personal social position, I have many ideas but still deeply hesitate because so far I can't see anything defined enough in the medium-long term. Schools was a deep delusion, at first I study at home with family selected teachers and with wonderful results confronted with my friends. At high school I decide to go to a school and the result was shockingly bad, I literally lived on income for almost all the time, having already more knowledge than the demand. At uni another delusion, programs seems to be designed to form Ford-model stereotypical workers just at an a bit formally higher level. That's was extremely demotivating and I do not know how can be for those who haven't even see something else.
Long story short it's more than mere no expectation: the modern society being way too elitist have deprived of any expectation anyone, promoting and rewarding mediocrity, crushing those who have personal expectations and desire with the clear aim of creating a society of useful idiots in the classic Greek sense, human-robots to be bolted is a pre-defined system. In that environment young can choose between:
- being criminals;
- being terrorists, as a sub-type of criminals whose target is more political and long term than for short-term profit;
- being nihilists abandoned on the screen to just see the world run as a spectacle.
I fear that there is no non-destructive ways out of such impasse. We are so folded in such a crappy social model that a war, a full-scale tragedy seems to be the least devastating option to change. History however tell that such movements never goes as planned, so plans are deeply needed and incredibly hard, while we all know that nothing will go according to the plan anyway, the needed plan is just a pre-digested guide to hope being successfully counter possible development in shorter times... That's stressful enough to made most just hopeless and a few minority neurotic and angry enough to being unable to do much more than quick shots guided by anger and emotions in general.
