DaasYochid-
Thanks for your opinion, but I’m not quite sure what you are disagreeing on.
There is a disparity in part because of the “age gap”. In my opinion, if every other issue was resolved the age gap would get smaller and the amount of single girls would go down.
I agree that shadchanim act that way because of the difficulty they have getting guys to agree to go out with the people they suggest. This doesn’t mean it’s right and they are shooting themselves in their feet.
I also agree that the vast majority of boys are married within a year or two despite all the problems (of which I fully agree with all the ones you mentioned). One of the reasons are, like I mentioned previously, that even when a guy starts dating, his pool will be much larger than the pool of a girl who firsts starts dating. In general, his pool will continue to increase while hers will continue to decrease. Another one of the reasons are, again like I mentioned above, is that it is much easier for a girl to fit the mold of what a guy is looking for than for a guy to fit the mold of what a girl is looking for. Hence the guys get married much faster than the girls do.
I even agree with your last point. What you have to realize is that guys run the shidduch market and I can’t think of any realistic way this is going to change. Like I mentioned before- when it comes to finding a shidduch- no guy is going to feel that he was placed on this planet to end the shidduch crisis and therefore he should only date a girl his age. A guy is going to look for the girl that best fits what he’s looking for, whether five months younger or five years younger. What the girls have to do (and I agree that it’s totally unfair and skewed) is to make themselves attractive (not in a physical sense) to guys closer to their age.
