Can you not understand that for you, with your degree and or other higher qualification all is well, but when you haven't taken any qualification since you left school life isn't quite so easy.
Those of us who have degrees do live in the real world, in which we have neighbours, friends, family and colleagues without qualifications beyond GCSE or A level.
I know plenty of people who don't have the magic C in maths GCSE and nonetheless function fine, as they got qualifications in plumbing, hairdressing etc and the latter qualifications are what is relevant in getting them jobs.
And I have known people who have Masters and PhDs who needed to go and get the magic GCSE grade C or demonstrate an equivalent qualification because it was a requirement of a specific job they wanted to do. (Not teaching.)
I genuinely don't think it helps parents and pupils to focus on doom scenarios for the future of this year's GCSE cohort.
