"I'd just love to know how you US and Canada guys broke the cycle"
US c-section rate is 34% at the moment.
Is that something we should be aiming for here in the UK? 
"I agree women should be able to CHOOSE natural birth if that's what they want"
You've got fuck all chance of doing that in a system where invasive and routine monitoring, high rates of induction and defensive obstetrics is the norm.
In that sort of system if you want a c/s, a birth involving loads of monitoring, an induction for non-medical reasons, and an epidural - you're quids in, because that's what everyone else is having.
World wide rates of assisted delivery are between 7 - 11% of deliveries according to this: here
The UK doesn't come out of that too badly at 12.5%, which is actually quite good considering that UK mothers tend to be fatter and older than everyone except Americans (who have a much higher CS rate).
Odd really, that despite an apparently vocal and bullying natural birth lobby around the world, the normal birth rate just carries on going down, and down, and down, no matter what women say they want.
