In terms of our historical treatment of our territory's indigenous inhabitants we're among the worst in the world, if not the worst. The life expectancy and living standards of Australian aboriginals were, last time I looked, among the worst of any group of people anywhere in the world. You have a better life expectancy living in Nigeria of Bangladesh than you do as an Australian aboriginal.
That's not to say that there haven't been some well-meaning efforts to solve the problem, but every other nation on the planet except maybe China has managed to get better results than Australia has.
Part of the reason for that is ignorance and denialism from Australians, along with a healthy racist dollop of blaming the victims. Which is not to say that the "victims" do not deserve a share of the blame - drug abuse, welfare dependency, sexual violence and similar problems can't entirely be blamed on the actions of either side.
Overall it's not a black and white issue, if you'll forgive the turn of phrase, but Australia's attitudes and actions are among the very worst in the world in terms of outcomes.
Hmmm, that's a fairly broad brush approach.
Agreed: The situations in some places are appalling - in all metrics, Australian natives usually rate way lower than average: life expectancy, general health, education, social problems, etc, etc.
Agreed: The blatant racist attitudes towards the "abo's" does indeed live on even today, strongly in some places (WA politician Wilson Tuckey got the sobriquet "Iron Bar" from chasing black patrons away from his pub with one).
Also agreed: Some "well-meaning" responses over the last 200 years have only served to worsen the situation for Australian natives.
However: Not all is lost. Slowly but surely it is improving.
Also some history: The Australian native lifestyle before white settlement was no idyllic, magic-pink-kangaroos dream-world imagined by some activists. It was a raw, prehistoric, hand-to-mouth existence with very few rules that involved constant droughts, disease, war, famine and other pestilences.
No aborigines that I have ever met want to return to that existence. They want to move forward too, but here's the thing: They want to manage it themselves at they own pace and using their own methods, with dignity.
