The flipside of the argument (I forget the economist's name but it was a Newsnight interview, within the past year or two) is that we absolutely *should not* revert to an elitist system because:
i) we have sent our factories overseas, to lands where the wages, whilst low, are actually high by their local standards. They are grateful for the long hours and can afford to get *their* kids a good education and a shot at the middle-class lifestyle.
ii) We have such a high educational standard in our part of the world that we shouldn't be plugging school leavers into low-tech factory work but should be exploiting their learning capabilities "to the max" (hideous Americanism, sorry) and building our economy around high-skills activities or products which we can sell worldwide. Apple is shifting millions of (pricey) units, for example. Maybe we missed that boat but the next big thing could be from these shores, if we churn out enough people with the right knowledge plus the skills and motivation to turn ideas into a going concern, instead of a secret hobby in a shed.
A graduate rate of 40% proves what everyone knew all along: there are a lot of really smart people out there.
In fact there are more very bright people around than there are job roles for them. Someone has to wait on tables, serve coffee or do other menial tasks because all the 'worthy' jobs are taken and anyone with one of those will hang on like a limpet, if they know what's good for them.
Indeed, a graduate's non-uni contemporaries will have 3-4 years' head start on them in terms of earnings (call that up to £75k more in pocket, or spent) *and* practical work experience. So, for any employer who sees the degree as irrelevant/excess knowledge, the more experienced non-graduate would be the person to hire for the job, if competing with one another.
Over their lifetime, the graduates are supposed to catch up and overtake in earnings but undergoing debt recovery deductions and trying to raise children at the same time can't be conducive to good mental health. If there's been no psychological fallout from student loans, after this length of time then maybe I'm talking out of my 'arris. Otherwise, let us wait and see.
