I grew up in a working class area, I never knew anyone that went to university. Wasn't even an option. I was 5 foot 10 at 14 years old. And looked about 18 . Our schooling here is
5 yo to 11 primary school
12 to 13 intermediate school
13 to 16/17 high school
Then Uni. All free until Uni. Uni used to be free until user pays came in. My daughter I put her through Uni then teachers college. My son didn't want to go to uni. He worked for me for his first 15 years.
I started at 14 nearly 15 and have never been out of work. I semi retired at 61.
