It's not bitter, it's reality. Dodging inconvenient truths because they make people uncomfortable is exactly the issue I'm trying to describe. The massive divide between what people say they do and what they actually do.
But if you don't believe me, do go ahead and create a fake dating profile. One in which you show economic fragility (which is the point of the OP article) yet that you're very much in touch with your feelings.
Enjoy the crickets. Nobody wants you.
Hence my point: be attractive, economically successful and only then might you also express some feelings. The thing you're missing here is "economically successful". You describe it as a basic life requirement but I made my remark in context of the article, which describes millions of men for which this is out of reach, even if they try. So the "mature relationship" doesn't apply as they won't be in any due to their economic status.
And as this lack of economic success leads to a lack of romantic success, they sink into a depression, start drinking, and then kill themselves. None of which apparently is worrying, instead the worrying part is saying that women select for economic success, as this sounds shallow, bitter or even offensive.
It's not offensive, it makes total sense from both a biological and cultural perspective.
