Actually I think it's absolutely the schools responsibly to try and tackle this horrid symptom of the chronic and gross inequality faced by children just now.
The fact that there appears to be a perverse enjoyment in kitting our your kid in an item that is so beyond out of reach of most children is really really sad.
If I was the head teacher of that school watching kids being made to feel shit because they can't have a 4 figure coat I couldn't stand idle.
What's next then - solid gold protractors?
