these people are victims of social views and policy as much as me. they aren't "hardcore drug use" they're people with a serious illness that develops as a result of something about our biology, culture, and environment.
i believe strongly in accountability. which is why i believe, as a society, we must hold ourselves accountable and that means facing the hard truths such as: any of us posting here is wealthy in some way and that wealth has come at the cost of suffering and death in some way. the very least we can do in this (potentially last?) period of widespread economic development is work to build systems that are humane and healthy. it's not going to happen overnight, and it will never happen if we build a world that hides the unpleasant things from the public.
we see the impact of the problem, but if your solution is to hide it then you haven't identified the actual problem and in this case externalizing the cost of actual human lives and suffering.
> I do not understand how you expect to have a functional, just, and free society based solely on individual accountability if you can just externalize human suffering and stash it elsewhere
You must accept that there will be some level of human suffering (quite a lot of it actually). It's quixotic to believe this will ever go away. All humans die eventually after all. Other than that, empathy at the individual level will bubble up in aggregate. This will vary from person to person. Some people want to go volunteer their time for charity, some won't. Again, this is all an immutable feature of living creatures.
