Seems to me its a very typical American response (not saying all Americans are like this but there's a large percentage) that don't like being told what to do, to change their ways and so on. It's the way they have been brought up, in this country it wasn't such a problem. Someone of expertise showing us what was wrong and showing our ignorance couldn't go on much longer. However having an outsider do that, no matter what his background is a different story. Would this country have accepted it if a foreigner came into our schools and tried to change things. I doubt it would work.
If someone can not see the method is broken, why fix it? Nobody would, plus the fact Jamie has all this redtape rubbish to put up with compared with this country where you can basically knock on Number 10 or local MP's etc and demand answers. It looks an impossible task, I'm watching this UK pace so I have no idea of the outcome but much like in this country, you can't just change the school meals, the home life you have to deal with the politics too. However America doesn't like change even if it makes sense, just look at this health bill thing. (Different matter, but a good indication of what I mean)
