I do kind of agree with the rules in your situation though - if you got a job, your housing benefit would decrease too.
But it's a bit of a sting with the postgrad loans when they count the money you have to spend on tuition fees. I think their 'average costs' are about as accurate as the 'average costs' they use to set housing benefit amounts, which are absolutely not what it costs to rent a flat where I live.
But such is life. I feel very lucky and grateful to have been supported by the benefits system since having my daughter (alongside working my arse off and studying, as although grateful, it is fucking soul destroying when they stop for no reason, and actually nearly drove me to suicide a couple of years ago - I can't wait to not need them anymore), and for not having an america-style university system whereby people go bankrupt due to student loans, and so many people are priced out. In your situation, you shouldn't actually lose any income in real terms? They disregard £500 for books etc. which is something.
PPs privilege are definitely showing on this thread though. I'm moving up the ladder, and am on the right trajectory to earn a great salary in the future. I'd much rather the money I pay in tax to go towards supporting a mum who wants to better herself, than one who has never had a job, and has no plans to ever get one.
Maybe this will all change when I'm old and rich - they do say this is what happens to young lefties
I doubt it though.
