I see your point but I don't think it is a major problem. If you have had or are having issues you can quite easily go to Consumer Affairs department in your state.
I think people need to take a certain amount of responsibilty for their own actions.
I'm 26 and have purchased 4 properties within 10km's of Melb CBD over the last 5 years, I certainly havent found home ownership difficult to achieve at all.
Are your expectations set a little high maybe? What have you found difficult?
