Apples to oranges. Australia doesn’t have the same society as us- nowhere near the levels of drug problems and drug cartels, and they are more likely to treat addicts like patients who require treatment than criminals who should be punished by locking them up with even more violent criminals. Australia has WAY better mental and phyiscal health care and better protections for workers. It’s much closer to a socialized society than the USA is.
As a result they have significantly different problems, specifically, they DON’T have anywhere near the same level of drug problems and violent crime. Their culture doesn’t glorify violence as much as ours does, and we don’t have that mixed in with a much more ‘FU you’re on your own’ type socioeconomic policy.
THOSE changes are why much of AU is a safer society. I strongly advocate for making many of those changes in USA. Specifically- health care should be a human right (including mental health care), we should treat drug addicts like patients not criminals, and we should otherwise reform our society for the benefit of the people rather than the benefit of the corporations in the economy.
