Exactly this. I've been single for four months at 27 and dated a lot during that time and I noticed that the bar is set _so low_ to place yourself as a better candidate than, let's say 80% of other men, that's it's simply scary.
Most men have literally nothing interesting to offer for a relationship. When you look at their situation from an objective point of view it's so obvious why they remain single and yet most are unable to see it. They either have no hobbies, hobbies that are almost exclusively shared by other men and often show no interest in their potential partners' hobbies. A lot of them also spend most of their time in online communities that are almost completely absent from women. They end up having discussion subjects and interests so far away from their dating partners that it turns into an awkward date.
