I read this and wasn't surprised. I had three paying part-time jobs at uni (including things like campus guide, which only applied every couple of months) and was the only person I know to graduate not in my overdraft.
Now times are more difficult and people are offering themselves for unpaid work experience (a fellow PG student offered, in an interview for a position I went for as well, to work for the company unpaid over the summer if they couldn't offer him the job - needless to say I couldn't afford to do this, he had the work experience and they didn't hire anyone when maybe a few years ago they would have paid someone to do that experience) it means there are far fewer options available.
TBH, I know that I don't have to pay my loan back until I earn above the threshold but if I were looking at the level of debt current students are then I'd be trying to make as much as I could to pay it off quickly - a debt is a debt and it makes you worry whether or not you 'have' to pay it back now. It is a huge sum hanging over your head and affecting how much you can pay in rent, whether you can afford children or any other number of life expenses - one of my friends was counting on her redundancy money to pay for extended maternity leave for her first baby until the SLC deducted the lump sum as though she was a higher rate tax payer (despite it being marked as redundancy and her having years of low-paid work with that company on their records) and refused to allow her to claim some back. It's that kind of attitude from the Student Loans Company that makes students panic about repayments.
