apushatayid & Dr. Pepper: What I said in my previous comment is a more accurate assessment of the issue. There are more girls (of all types cumulative) available than guys (of all types cumulative) available. Therefore, your point — as true as it may be — doesn’t get to the root of the problem. Even if the girls would forget all their meshugasim and be willing to marry any ehrlich boy — or even if she would be willing to marry ANY frum boy [and he willing to marry any frum girl] — the problem still exists, as there are more total frum girls in the entire shidduch market than their are total frum boys in the entire shidduch market.
For that reason, also, the shadchanim have no leverage over the boys, and must cater to the boys whims and they can’t do anything about it. The shadchanim have to be afraid the boys will ignore them (while the opposite is the case with the girls), while the boy doesn’t care if the shadchan ignores him.
