I agree with this.
It also wasn’t good in the 2000s in my secondary school. We had a teacher who divided their time between teaching science and giving us careers support. I didn’t get any specific or practical advice from her - and nor did my sibling who also went to that school.
That secondary school was objectively a good school (medium class sizes, generally good behaviour from kids and teachers who mostly taught their subjects well, supported and believed in us and wanted us to do well). The sixth form I went to afterwards was even better, using this same criteria, and I can’t remember getting any careers support there at all.
I got more helpful careers advice from my uni careers service, which I still find relevant today.
