There is another factor that is major which needs consideration. Mental health care. It is dismally inadequate. Which is why mass killings are as common as they are. And, domestic violence is as it is.
The reason you do not know about this is because media, courts and local governments as well as the state are colluding to keep the public ignorant. Yep. a conspiracy, and its big. Here is what happened when I filed a suit against my county in federal court and gave a copy to a news reporter who had shown courage relating to drug issues.
What happened is she was fired. Sixteen other reporters and editors joined her and they were all gagged by the California State Superior Court. The same court that had been depriving me of justice since 1997.
What's the conspiracy about? Its about keeping the ultimate methods of secrecy, secret. What is unconscious is BETTER than secret. Effective mental health care MUST address the unconscious mind directly because that is where the disorder really is.
Here is a page which is fairly recent that supports this position.
