I'd ask how good the two guys in question would have been if you'd picked them up at sixteen or eighteen and trained them in house/given them apprenticeships where they trained on the job/etc vs how much better off they and you are because they dropped tens of thousands on a university education (as well as missing out on a few years of earning). And I'm not sure what they studied but just a quick look at Westminster and the courses I opened were all BBC, so a jump from where I said (I'm not drawing the definitive line in terms of what grades/subjects combos are appropriate, btw).
Well perhaps a jump now, I'm not sure what the grades were at the time without the degree course or experience they'd not have the skillset/background we'd have been after (though a-Levels grades have experienced some inflation too over that time period, today's B is more like a C from a few years ago).
As for training 18 yr olds in such a role, IIRC there was one such case who moved from an in house IT Helpdesk type role to an operations type role, but it was more a case that he was already hired for the basic IT role, had that for a couple of years and started slowly taking on a few ad hoc roles relating to his next role. That isn't sufficient in itself terms of recruitment (the teams concerned being significantly larger than the small team performing basic office IT jobs that one guy came from) - if someone leaves you want a replacement fairly quickly (that usually requires experienced hires) and if you're looking to expand the team over the next year say then that is where grads who have a certain basic level of knowledge come in. But yeah the support team and the similar ops team were composed of a mix of grads and non-grads and there certainly wasn't any rule that said we only hire grads for those roles, it was just useful to do so in some cases - you'd pay 40-50k for an experienced guy for one of these roles whereas you could pick up a grad for 30k who'd be happy with say 3-4k pay rises for the next few years and can sometimes be just as useful as the guy on 50k.
I should further stress that throughout this discussion I've been saying how I wouldn't write off any degree or institution, and nor would I fawn over particular ones... I'm interested about quality. I want to get rid of rubbish courses regardless of where they are and what they are, whilst preserving and focussing on the worthwhile courses. I'm pretty sure we can both agree that there are a significant number of courses which are a waste of time... it's about identifying them.
Indeed - though perhaps with fees at 9k per year there is increasing pressure for such courses to justify their existence, maybe pressure can be further applied if all courses were forced to make clear certain stats re: % in employment, % in post grad study and perhaps salary range of grads and types of jobs they've gone into so that 18 yr olds aren't under false pretences re: their general prospects after studying particular subjects at particular institutions.
