Living away will become a luxury for a minority (like boarding schools) with most living at home.
The generation of current parents struggle with this as they were the generation where more went to uni and must will have lived away. Living away is so tied up culturally with UK perceptions of getting a degree. But that is increasingly something of the past.
Parents who went to uni often have fond memories of living away. It is inextricably linked with their degree and growing up, in their minds.
But of course, one can get a degree without living away for uni. One can learn independence and most will eventually live independently away from parents without difficulty, even if they don’t go to uni or don’t live away for uni. But they probably won’t do it as teens.
The finances of it mean that people will have to separate the 2 ideas of living away and studying, in the same way most families send their children to local rather than boarding schools.
Before the 80s, few went to uni and went away to uni. Increasingly we will revert to that previous pattern of fewer (usually the most affluent) going away.
It’s a reality. And yes it probably means less social mobility. Yes, lots can get degrees close to home. But fewer will be travelling and living at elite unis. So access is reduced and narrowed. But it’s a sign of what our society can afford and the polarising of access. Whilst access expanded after WW2, including elite access, that is now reducing.
