artchill, why do you assume that women who move out of town to further their education consider themselves superior to others? I know many women who’ve moved from smaller cities (such as Chicago, Cleveland, or cities with smaller Jewish communities) to the NTC area. Most of them moved for both educational/ job reasons & for shidduch purposes. The women I’ve met don’t have a superior attitude about this. Apparently your experiences are different.
I only mentioned the fact that many women move for shidduch purposes (especially if they are older than the average single), so your 2% data point may be artificially low (what is your source for this, by the way?)
