A lot of people have very arrogant attitudes towards graduates who can't find work.
On the one hand they say LOL you went to an average university and did an arts degree LOL as if you're gonna get a job. Then on the other hand they say why don't you have a job you could get one if you really wanted....?
I can understand the graduates who don't want to just take 'any job' eg working in MacDonalds or doing a data entry type job because it can be a CV killer to an extent. Think about the graduate schemes who want exceptional candidates, they are looking to identify high fliers. So when they are looking at a load of 21 year olds who are in their final year at uni and have great ECs etc they think "potential". When they look at a 23 year old who got a 2:1 in History a couple of years ago from a decent uni, then worked a £15k a year admin job for the council they think, hmmm "data inputter".
One of the big myths from the older generation is you can get a job and start at the bottom and work your way up. You might have been able to in the past but it's pretty rare now. When companies run graduate schemes, they are targeting graduate recruitment at people who they see as having potential to progress, the other staff they have are just to make up the numbers on the lower salaries at the bottom. If you get an entry level job where you're just photocopying, filing and answering the phone, then no matter how great you are at that job you will still be doing it in 2 years time, they won't promote you to a graduate scheme. So you won't have any new skills to update your CV with.
This is the big underemployment trap a lot of grads fall in to and I have seen it with quite a few people I know who graduated 4 years ago now, they are all on these admin/customer service jobs earning between £14k-£20k and with no real hope of progressing to further. There are a LOT of bitter disillusioned graduates in these type of jobs who are late 20s/early 30s, and have the attitude "I coulda bin a contenda" moaning about why they went to a good uni and got a 2:1 and they thought life would have been better than this...
