I don't agree individualism is to blame. I think we are seeing the consequences of nihilistic secular humanism as drilled into the wider culture through education, the media, and politics. How you feel matters more than how you reason out a position. Central banks and fiat money have wiped away opportunity by consolidating wealth, but people blame "the free market." And kids with no purpose, often from broken families, with no moral role models beyond TikTok have no reason to strive.
Where has this come from though?
There has been a push for the last 100 years to drive people to toward isolation and away from family. Perhaps it ramped up more since WW2 and after so many men were killed, pushing more women into the workforce also. Women used to be the social glue that held communities together at the local level. It is all part of the meta.
It is "free" - the banks are exerting their freedom to control ;)
This is a direct result of profit at any cost consumerism that has resulted in the development of applications and algorithms that compete for attention. That attention is taken from elsewhere - which is ultimately away from interacting with other humans directly and locally.
The entire economic algorithm for profit rather than wellbeing creates an environment that has encourages that nihilistic secular humanism you mentioned.
I think your cause-and-effect analysis is flawed.
Placing all the blame on corporations and none on the people who choose to consume as if they are automatons seems to be missing a big part of the picture.
Addendum:
Consider the wider trends, not just delinquency, but also depression, anxiety, suicidality, gender dysmorphia, and other indications the young'uns are not OK in a wide range of areas.
