I'm not asking for double minimum wage, I'm just hoping I can get another 1 or 2 pounds an hour!
It's not about how much more you're asking for though, it's why. If you were saying 'I already get X amount from my parents so it's not worth getting out of bed for less than £5 an hour' I'd think you were spoilt and greedy, but right now it's somewhat justified if you're putting that time into studying. It's an attitude that would still bite you in the arse when that support is taken away mind.
You're not though; you think you're better than minimum wage, but you're not willing to prove it by taking the poorly paid position, working your socks off and getting promoted into a position above everyone you think you're better than, and sorry but that just makes me think you're immature and arrogant.
Yes you should look at the options and take a position with whoever offers you the most rewarding opportunity - be it monetarily, experience or enjoyment - but you've not found anything yet and it's the casual shunning of what is available to you that is just sad, but unfortunately common.
There's a lot to be said for the ability to knuckle down and if you came to me at 18 with no references and all A's asking for a job, you had better hope there was no one with similar (or even 'adequate' grades depending on the job) that they'd funded by working full time in a poorly paid job for two years going for the same position, as that shows a level of discipline, graft and maturity that too many people lack.
