I agree. The thing to keep in mind is that this works against men as well as women, it just hits them at different points in their lives.
If women between the ages of 21 and 25 are interested in (and pursued by) men between the ages of 21 and 35+, while men between 21 and 25 are limited to women who are roughly the same age, then men will face a very difficult dating "market" in their early 20s, and women will experience a favorable one. As men and women age, the inevitable symmetry switches the situation - women between 35 and 40 are now competing for men who are pursuing women between the ages of, say, 25 and 40.
This is something to keep in mind when you hear that the dating world is unfair to women over 35. It's "unfair" to men too, just earlier in life.
You're right, life gets tougher for women after 30 but I am not following you in where does this benefit men?
According to your analysis a larger pool of men 21-40 are always competing for a smaller pool of attractive women 21-30, so if you're a single male, the ratio is always against you no matter how old you are.
And that's what I'm observing in real life. Perhaps I'm too young, but every public gathering I go to features a disproportional number of guys. And if you subtract overweight people from the picture, the ratio gets downright scary.
Some guys are like that. But in my example (or I guess you could call it my model), I had guys interested in women at or below their age, and women interested in men at or above their age. In reality, it differs for each person, but average age preference is probably a right or left skewed bell curve for women and men.
And of course, women probably aren't attracted to older men simply because they are older, they're probably attracted to the life and professional accomplishment, maturity, financial resources, and so forth - sorry bruddas, but merely aging is not going to help things here.
On the flip side, the numbers really do start to look grim for single women as they approach 40. A lot of women enjoy the dating scene when they are in their early 20s, get married around 30, and stay happily married their whole lives - and never really feel any of the frustration of being on the wrong side of the dating equation. However, this means that most of the disadvantage gets concentrated onto a fairly small number of women, who basically get the full brunt of it.
