This.
I've heard senior academics admit the system is screwed up and tense and they wouldn't genuinely advise many YP to go UNLESS they're super focussed and pragmatic and see it as a "means to an end".
All the news stories about bullying, the students not even getting their degrees in the strikes...that's the tip of the iceberg.
The time of it being about personal growth and chilling down the bar and meeting new people from different backgrounds (whilst on full grants) is over.
Universities are doing the "hard sell" to get the numbers up (targeting fairly aggressive, dishonest outreach at POC and women, all to get more money for old white men).
But often the social mobility can be incredibly low once the students have actually signed up and are in the system. You see all the people from similar backgrounds flocking together and quietly excluding anyone else.
(You also frequently see "non-traditional" people being manipulated into paying massive amounts for Masters degrees as if that will make them "fit in" - but they're just treated like cash cows with no good job at the end).
I agree with the take that a lot of non-international students have opted out in terms of going home for the weekends, and not having a campus social life beyond the minimum.
Pragmatically as I said, I'd focus on getting that 1st or high 2:1 and utilising any opportunities for placements or resources.
Either get into the graduate corporate milk round or use the time to upskill/build a side-hustle (university is the ideal time to do this, as they're living on a shoestring anyway so don't need to bring in extra income immediately).
Make allies and find people who can be references. Or use the time to pick up AI skills and get a grip on investing and financial planning and what's happening there.
I wouldn't throw good energy in places where nothing is coming back.
