“It really doesn’t; it merely assumes that there us one factor, which if not dealt with, will continue to cause an insurmountable disparity.”
See this is a perfect examle of the simple mindedness I was talking about. There are probably any number of factors that would cause insurmountable disparity – if viewed in isolation. But the different factors interact with and mitigate each other. If you want to be an oiber chochom and get so tchnical that you truly believe the shidduch world IS an island, you are going to miss some pretty relevant data.
And hiding behind the skirts of talmidei chachomim is a pretty lame defense, IMHO, which has grown exceedingly tiring.
