I was reading this article on The age and I was naively amazed by some of the reader comments. I'm a research student living off approximately $25k per year (no scholarship- I saved up hard to buy the trumpy). I was quite happily thinking that, for myself, $50k a year would be plenty to live happily on. After reading comments on theage I feel I must be living like a bum. How much is enough for you? How much is enough to raise a family?
