The thing is, there is a huge amount of snobbery around this, much of it ignorant and misguided.
If you work as a top engineer (say) and you know that there are 3-4 departments in the country that really produce the goods - fair enough.
But I hate all the employers who come on saying 'Oh, I just chuck out the CVs with non-RG degrees on them.' I teach at an ex-poly and believe me, the best students are just as bright and high-achieving as when I taught at a 'top' RG institution.
It's often a discreet snobbery against poorer kids. Because these days, kids whose families have less money will often go to the 'local' university to be able to live at home or have a short commute. That will often be an ex-poly.
But the snobbishness...? It's ridiculous. I did my first two degrees at Oxford (not a boast, just a fact) and there were certain colleges that everyone looked down on. I mean, ffs. It's all just desperate self-validation.
We also used to chant 'I'd rather go to Durham than be a Tab [at Cambridge]' which is surely the ultimate wanky snobbishness
Every time I hear someone talking about RG I get that chant in my head!
