I'm around 11 years older than you.
I know my experience isn't especially portable as I went to a public school in the home counties, but not all of my friends did, and while I understand they experienced teachers with varying levels of competence and interest, none of them has described it in as harrowing terms as yours, and all came away with friends and a fairly decent education, albeit one that they probably had to have a bit more determination to get than I did.
My mum worked in various UK state schools as an assistant from around 2000-2010 and described serious budgetary problems throughout the system, and teachers trying their best in adversity. She also described the many obstacles in the way of getting the bad kids out of classrooms so they couldn't disrupt things so much. I have a friend who teaches at a grammar school, who is fairly intelligent and interested in his subject, and seems to teach well to kids who are interested, though again there seems to be little money to achieve anything.
I'm not claiming shitty, prison-like schools don't exist or trying to invalidate your experience, it was clearly terrible, but I'd be wary of drawing too many wide-ranging conclusions about school education as a whole from it.
