So in your dream society, mentally ill people will be incarcerated for life and charged for it. You think that someone who is so ill that they are a danger to themselves or society is going to be able to pay for 24/7 medical care.
That's delusional. Really even for a person who doesn't like to deal with the real world such as yourself, that is daft.
Are we to assume that these mentally ill people are violent and incapable of survival? Are we also to assume that these menally ill people don't have parents, friends, or other caring individuals (charitable organizations) who would want to take care of them? A similar argument could be made about children.
That's delusional and daft too. I've seen the real world, and much of what I see doesn't impress me when it comes to government intervention programs.
Try to think outside the box, and stop insisting you need society to mollycoddle you so much.
You think care of the mentally ill is mollycoddling! Are you totally cut off from the real world? Right now over half of all who are imprisoned in the US for violence are mentally ill. You can't possibly expect poor families to cope with the 24/7 care of violent ill people.
Please stop trying to avoid the reality that there are people who are so dangerous they need to be locked up. And offer a semi-intelligent way for their 24/7 care to be paid for.
