I agree it’s not accurate to lump all mentally ill people into a category of having bad brains. And I also agree early intervention is probably the best means to prevention, although I don’t really have any evidence to base that on aside from observing life for 30+ years.

But, I think it’s also counterproductive to pretend that we currently have the knowledge and technology to turn all of these people into productive members of society. Some of them have indeed been dealt a bad genetic hand, and giving them a house isn’t going to fix it. The guy yelling nonsense at the sky and stabbing people needs more than I know how to give him, and it’s too late to make sure his parents feed him his green beans.

So, I’m definitely open to discussing medium and long term solutions, and investing tax money into helping this problem have reasonable outcomes for all the badness involved. But I’m not happy to wait a generation for these to take place, and just hope these violent maniacs don’t kill someone, or throw a five year old kid off the upper floor of a mall...oh wait, that already happened.
