Whilst an interesting article, are we really surprised?
We live in a society ran by elf'n'safety et al meaning that kids no longer learn about the real world and instead grow up in a bubble.
When this bubble pops, they realise that the coursework based education they've received, at mollycoddling schools where they don't play outside for fear of getting a grazed knee, whilst teachers can't discipline or even educate for fear of lawsuits, has all been completely pointless in the real world.
They continue to run on the same tracks they have been taught to run on, and instead of rising to meet the challenge (something they are never taught or made to do), they write it off as being unfair and feel like the victim.
When we bring back conkers in the playground, cross country runs in the middle of January across frost covered fields for PE lessons, discipline in schools and an education geared towards learning and real life instead of nice looking statistics for whichever knob is currently in power... Maybe when we do all of that, we'll have a future generation capable of achievement.
I won't hold my breath though.
