Completely untrue. I may as well not have a degree
For the vast majority of good jobs that will give you a career, it certainly is true.
Again, total bollocks.
And anyway, that isn't how you phrased it. You outright said 'a 2.2 is bad' therefore invalidating the degrees of millions of people. What gives you that power?
It's not, the only chance you have to get a decent job with a 2.2 is to find somewhere to do a PGCE.
A 2.2 isn't a very good mark, especially if that qualification isn't in a hard science or in computer science, it send a bad signal, i.e. that you spent most of your time getting pissed.
If you look at any graduate job description that pays good money you will typically see '2,1 or above in a relevant discipline'.
I got my graduate job with a 2:2, which I like to think is a pretty decent career with a pretty decent company.
Company was recruiting 2:2 and above.
