Two things about your observations about 37:
* Hex 37's not unusual in having variations which are 'less than ideal situations' imaged in the individual lines - most of the hexagrams have that.
* The idea of a dysfunctional family is a very western phenomenon. If you go to places like Tibet or the Phillipines, family has a much more positive value in people's minds; it's only in the west where in some circles 'family' is a bit of a dirty word. So if you see dysfunctionality in family, that's one thing; but if you think that's built into the meanings contained in 37, I think you're seeing something there that the authors never intended. They were aware that sometimes things go off track (check out 37.3, for instance) but for them the family had *such* a positive value.
Finally, you talk about the top line being incorrect. What do you mean by that? I see no indication of incorrectness in 37.6.
