The issue is the overall snowball effect: that is, when you get 1 characteristic it is also highly correlated with several others that almost by definition come with it. This is the problem with modernity and women in a nutshell. As Kanazawa said, time hurts women, and helps men. That means the things men look for are almost all associated with youth. One of the dumbest things as a response to this is, if they're scrounging, the appeal to male attractiveness by the female, pretty much only a modern day spoiled phenomenon. The proof that it is nonsense is that at least the man has tradeoffs. Again, the 30+ woman doesn't have a benefit for all the costs. Especially when the society does not, or cannot do, anything to guarantee anything from the woman. Another one of the funny delusions is the "but he might die" earlier than I do, as if that doesn't happen already or is a guarantee. What's more, the point of the gap is the known fact that the man is eatablished.
