We had the same after the Olympics, when someone was complaining about how many of the athletes came from public school backgrounds.
And some blame can rightly attach to public sector teaching staff.
I recall an interview with Wiggo around the Olympics when he mentioned his earliest ambition to be an Olympic cyclist, when at a State School in Kilburn.
"Nah", said the teacher, "kids from round here don't do that sort of stuff!"
And that was the PE teacher/Games master!
