This isn't a new concept Drlee. Haven't you heard of Durkheim's suicide study from 1897?
I have and I am aware of his four classifications and their societal linkages. This study is 120 years old. Many of the bright lines he saw (such as the difference between Catholicism and Protestantism) are not so bright anymore. He lived in a world with draconian psychiatric interventions. Distinct and very unpleasant results followed any claim to what was then thought of as insanity.
I am not rejecting his work. It is still observed. But times have changed. We have interventions that are vastly less devastating in themselves, a society far more comfortable with the concept of treatable mental illness and access unthinkable in the 19th century.
Durkheim focused on social and societal influences on suicide. True enough. But in the 19th century there was little awareness of organic causes for depression and its link to suicide. It was thought to be a combination of heredity and weakness of character and was treated by locking people up. Not so today. Right?
Don't think for a moment that I believe that societal influences are not important. I do. Why else would 70% of suicides be white males?
So look again at what he said:
It is a flaw in out society because (in the West anyways) many people are self-absorbed and don't bother to check how the other person is doing.
Does this fit what you and I know? I think not. It is overly simple and, in my opinion not proved. We are far more connected than people in the past. The question is the depth of that connection. That would be fun to discuss is some more uplifting context.
Then he said:
Additionally, the west does a poor job in terms of mental healthcare -- It is still a large stigma and many people regularly fall through the cracks.
But compared to the 19th century? We are vastly more competent and care more accessible than ever before. And in terms of effectiveness there is no comparison.
If I were wanting to be cute I would assert that in Durkheim's day the very thought of treatment for mental illness would be a pretty good reason to consider suicide. Let's not go there.
To the larger question. Is suicide a sociological phenomena? Sometimes. Maybe even much of the time. But does its prevention lie in far reaching social change? Nope. It lies in helping the individual cope with both physiological distress and appropriate adaptation to their situation. An analogy? People have to learn to grow where they are planted. Sometimes they need a little fertilizer. Frequently they need the services of a really good farmer.
