@mellongoose circumstances leading to a change in public support requirements can change very quickly.
My young son had an autistic breakdown (I didn't know what that was at the time). An extreme crisis that happened very quickly.
There was no immediate medical support at all, nothing. An "emergency" Camhs referral (rarer than hens teeth to get) took 4 months.
Thankfully due to peer support groups I was able to find support, legal advice and eventually private assessment and support. I could not and should not have done this alone as to begin with, I had no knowledge of Sen.
I consider us lucky, private assessment, research skills etc meant we swam (flailing more like!) rather than sank. That I wasn't prosecuted for my son's absence.
Others are not so "lucky" - 3 year waiting lists for assessment lead to suspected neurodivergent children not having their needs met in school, often absent. Their parents prosecuted. There are 20,000 people in one support group. There are many support groups.
Your view isn't contraversial really, it's quite populist. But it isn't correct.
