What Labor is proposing is in no way impossible as some people have made out. Denmark, which has similar demographics to Australia and most other western countries (aging, fattening population), and is capable of paying entirely for university for those who deserve it, according to merit.
What this comes down to is whether it is whether you believe anyone should be able to achieve any position in society regardless of family wealth. I, like Triangulum, am of the belief that if someone is smart enough, that should be the sole consideration in awarding them a university place, not the size of their parent's wallet. Those of you that think otherwise, I ask, would you still think that way if you were poor? I very much doubt that. My parents could afford for me to go into a DFEE position, that doesn't stop me realising the intrinsic unfairness in your argument.
That government-owned farms proposal is different to University, as everyone (even those on centrelink payments) are able to afford the necessities (but not the lobster, as that is a luxury item - I have no problems with someone having to work to buy that). If we were in a serious depression however, and starvation is a serious issue, I would support rationing and other measures (rationing actually occured in WWII in Britain, dunno about here). University is different however - if all the courses cost you $5 a year, I'm sure there wouldn't be much argument against having entirely DFEE, but in reality they are obviously not. University in a large way is responsible for the careers that are open to you - Medicine, Engineering etc, and so thus should be given according to merit, as everyone deserves a fair go and this is what egalitarian societies do (very foreign ideas they are right?).
