half of all australian families pay no net tax, page-31

I have a question for you who don't believe in family tax etc,

What about all the people that had their uni education for free? Should they pay funds now to compensate?
Can you explain to me why I can be in the same tax bracket as someone but they may have had free education and I had to pay? How is that fair?

So yes, if I get help from the government in the form of Family Tax Benefit, maybe I deserve it because I paid for my education and some people didn't.

I know that Chris Pyne said we only pay for 40% of our education and I'm not insinuating that you got your education for free, just trying to point out that maybe some people get/got some things for free when now people have to pay for them. Maybe it evens out in the end.
