That's an interesting anecdote, but I think you need to be in for a penny in for a pound on this sort of stuff.
Truth is, I'm playing devils advocate. I've worked in tech for 15 years and have bought a house in a good free school area, so it's a bit hypocritical, but I don't overly believe the US or the UK has the best education systems.
You could argue they're the best at the high end. Indeed, Ivy League and Oxbridge has some of the best reputations in the world, but interestingly, most of the Red Brick pulls in rich kids (especially Oxbridge), which recently have been exposed for having easier exams (in the UK), which complicates the issue.
Are they the best because they're the best, or because they have all the money?
Blah blah blah, different colours of grey.
