I don't think anyone thinks that there aren't huge issues in some communities but a huge part is disfunction that was created by poorly thought out policy in the past. Taking people from their families and institutionalising them, molesting them in some cases, removing them from their culture and land, not even considering them proper citizens until the 1960s.
It's not like "just get over it" and move on is an answer now. Psychology acknowledges generational trauma that gets passed through DNA. There are no easy answers but not trying to do something is also not a great option. Otherwise it just continues a broken cycle.
The voice isn't going to fix everything and maybe nothing but it gives them some feeling of agency in their own affairs. Aboriginals used to have to apply to move around to their protectorate in current living generations.
We helped create the mess so own some part in helping to fix it IMO.
I'm not advocating for a no vote.
I'm yet to really look into it. I will before I vote though and then I'll make a decision.
