Let me just take a moment to register monumentally huge agreement with your modification of the the metaphor at hand. The problem here is that
huge numbers of other people are living in almost
exactly
the same circumstances - or ones that are objectively worse - and they register
no depression.
And here, by objectively worse, we're talking, risk their lives daily on a shoestring lifestyle that barely keeps them from not having a roof over their heads and rice or beans enough not to starve to death. Do those who risk their lives have something the comparatively wealthy depression cases lack? Are the kinds of pressure the relatively wealthy depression cases experience particularly likely to create this kind of response? What's the difference? What's the root cause?!
If we had actual, good root causes, then we'd be golden, but the problem, the HUGE PROBLEM that the paradigm espoused in the article faces, is that we DON'T have a kind of 'smoking gun' need that is not being fulfilled for people with depression. MANY, MANY people with deep depression really do have fantastic lives compared to those who suffer no depression- and moreover, admonishing people with depression to 'figure out what need is being unfulfilled in your life, and fill it' is highly toxic advice, at least in its way- based on my experience with depressed individuals, if you effectually tell depressed people to figure out what's wrong in their life and fix it- well, it's one way to obliquely encourage suicide.
