Just imagine how we need to change the system of health care and society so that we can identify psychological problems at an early stage, because most people will never admit that they have any problems on a psychological level, although very many people have such problems to a greater or lesser extent.
In my opinion in order to do that we would have to introduce stricter control over each of us, and no one would like that, so society will never get rid of inadequate behavior of a certain percentage of people. We'll just have to accept it and be more attentive to our children and loved ones to protect our families from it.
But this relates only to situations that can be looked at over a long period of time. How would a system treat people that have a life-changing experience and then crash psychologically? That isn't something which can easily be predicted or anticipated. In my oPinion one of the safest situations is if someone has a healthy social environment and doesn't isolate themselves. That is when people can detect changes or even know that someone must be suffering and took a bad turn in life. Otherwise you would have to allow the health care system to be very intrusive and value all data that ever is collected about someone. That doesn't sound very good to me.
