50% of people going to university is probably too much though even if you want an educated society.
And if we are talking about an educated society what do we actually mean here? A lot of criticism has been levelled at how younger generations have been taught to pass exams rather than think critically or apply practical lessons to real life. Or have practical life skills generally.
And then we have huge numbers of people who don't understand how mortgages and pensions work even though they went to uni.
An educated society doesn't necessarily mean university educated. In terms of practical life skills we've definitely regressed as a society and this doesn't help. What was expected of 14 year olds as a society is massively less now than it was decades ago and I think we should be thinking about this as much as thinking about university education as there's actually links to the state of society as a whole on many levels.
Our values about what we consider and prioritise as education are very much part of the problem. We have a society which looks down it's nose at 'the uneducated' yet we had many people who achieved professional careers who left school at age 14 or 15 who will eclipse this generation of degree educated kids. This matters too.
If you don't go to uni, there's an attitude of 'youve already failed' and barriers are up that weren't there even a generation ago. That's wrong. I don't think we are getting a generation of workers who are necessarily better.
I know how many employers don't like taking on fresh graduates because they have no idea how to do anything in the workplace as their knowledge isn't transferable directly from the classroom. So they want people with experience instead. Which creates the whole catch 22 of how do you get experience if you can't get a job in your field.
In reality we have lots of people with degrees in areas we don't have enough jobs for and we have a short of educated people in other areas but we still can't give them a job because there's a lack of places in the vocational training part of that career. There's more people who want to be doctors and midwives etc than places to train and yet we still have a shortage of doctors and midwives!
Our whole education and employment structure is off. And tbh I think this is where issues really lie rather than actually with faults in the student loan system itself.
