Kids finish education at 16 and by 14 are more-or-less required to know what they want to be when they grow up. By 16, they need to know as there is not the forgiveness in "path" as there is in the USA.
As a Brit who has gone through the U.K. school system, I have to disagree with most of this.
In England, education or training of in some form is now compulsory to age 18 (whether that be Sixth Form, FE College, apprenticeship or 20 hours a week of volunteering/training while also in part-time education):
https://www.gov.uk/know-when-you-can-leave-schoolWhile you do have to choose your career path younger than in the US (you decide your major before you apply to university), you don’t have to choose what you want to do when you grow up at only 14... not at all.
While you do give up some subjects at 14, you still take 9 or 10 subjects (with English, Maths and Science compulsory, along with a language and either history or geography (and you can take both)), and you don’t narrow down any further until age 16. From the ages of 14-16, I took English, English Literature, Maths, Double Science (with classes split into Physics, Chemistry an Biology), French, Geography, Home Ec and Theatre Studies. We still had to take PE and RE classes, but they were extra and not graded. The only subject I dropped which might have been helpful later in life was History.
When I was 14, I wanted to be either a journalist or a make-up artist/beautician. At 15 I wanted to be either a journalist or a lawyer. At 16 I wanted to be either a geophysicist, or a French translator, or a dancer (I almost left school at 16 to go to dance college). By 22 I had a degree in Physics. At 24, I had a masters in geophysics. At 27, I became a meteorologist. At 35, I’m still a meteorologist and I love my job.
