There's always going to be a huge salary differential, a startup might pay a graduate £20k/year while an investment bank could pay the same graduate £40k/year.

So I'm not sure if higher debt is going to sway people's career choices (especially given the way the debt is structured means you can make lower payments if you're earning less). Although it is one of the major arguments in favour of a graduate tax as opposed to higher tuition fees.

I guess we'll have to wait and see what impact it has in practice.
