I don't really know how it's distributed. There seems to be a generally stronger streak of anti-intellectualism in America than in Europe, and kids probably pick that up. A poor primary education system may make the problems worse by making education gaps wider and by leaving children with a poor grasp on how the wider society functions.
I've the impressions that things are somewhat more US-like in Britain and that studying science is more appreciated in the former Soviet bloc, but I don't know how accurate these are. Education seems to be very highly valued in China and India. I've no idea about the rest of the world.
Yes, Britain has a similar culture to the US in terms of children punishing those who get good grades. My personal experience was that getting good grades was not in itself a major problem as long as you didn't appear to be trying too hard or to care about the outcome.
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
