We are too busy buying houses to invest in businesses including miners. There are some good little up and coming miners which may start Australian owned but we don't back them. i.e we buy houses and not their shares. So the company trades cheaper then it should and get's taken over by overseas investors. I have put my money in and now you communists want to take it or tax it. That is exactly the problem with Australia, we buy non productive assets like houses hoping for the next dope to pay more. It can go on forever, not.
