Just to chime in on Roger's patch.
I've been baffled about educational standards for some time. I mean look at the people with degrees who can't see a simple pattern to the f stops. Or spell "colour" correctly ;-)
Anyway, a friend of mine is involved in standardising standards in education and he reckons an American degree is worth a 1950's "A" level at the most. OTOH, he reckons a PhD from the best USA or UK is the same.

PS And these days the Govt. say everyone should have a degree: that hardly suggest we are talking about the top 5%, does it? And I reckon an apprenticeship is worth its weight in gold. Certainly, it's a lot more use than a degree.
