Not sure of the point here. Anyone with actual standards will be single longer. That's what standards do. Minimize the potential pool.

Women without standards themselves will not do well looking to date these men because their own lack of will exclude them. Same thing with what happens with women who have real standards but in reverse.

I doubt women are excluding men based solely on age as you suggest. If there is a significant amount of rejection, it's likely that there is some other mismatch. Like, he wants to settle down, but she's just dating to see what's out there. He's a great guy but doesn't have a lifestyle that is good match to her personality and she's self aware enough to know it. One of them wants children but the other doesn't. Theyre both great people but there's a personality clash. There's all sorts of things that have nothing to do with whether either one of them is a "good" or "bad" person.
