he doesn’t even present any evidence that this was caused by some failing of the schools

The cynicism I've gained over the last 7 years tells me that there's an agenda being pushed there.

EDIT: To elaborate. I'm not arguing whether "the agenda" the author has is good or bad, but it's off-base. If you're reporting on a story, you really should leave your feelings about the story at the door. It's not like the story isn't interesting enough! If this were an op-ed, then that's one thing. But the "sensationalist reporting aside" and "we can't help feeling sad" and then pointing to... the UK's education system... it's clearly not objective. You're not presenting facts and facts alone, you're presenting facts with your opinions mixed in.

Just look at what the author invited into his comment section with that:

Not enough male teachers for these lads to confide in and see as role models.

Blatant sexism.

Yes, keep male teachers who are not woke away from kids.

Groomer accusations.

If I had to guess I would pick serious mental illness rather than a failing by the schools.

Disparaging of neurodivergence (neurodiversity? IDK if that's still the right term). Hacking into companies and bragging about it is something even neurotypical teenagers do.

bigfoot, the loch ness monster, a functional education system. list of things that don’t exist.

Anti-education screed.

As for the energy, I suspect actually getting laid, probably for the first time, would likely help.

Do I even need to say anything about this one?

You caught a lot of downvotes on the original post, but it is reductive. I pretty sane conclusion but educational support probably isn't the only culprit, issues like this are multilayered and not so cut and dry.
