It maybe abstract to you.
It is relevant to woman who beleive without their husbands they will never be able to live for eternity in a celestial heaven.
You say, there are tons of non depressed lds women in DC, and you would know this how?
It is extremely important to lds to never ever let the outside world know how they feel about anything. They must present a "perfect" shell to the outside or they might sully the lds church.
I'm comparing anecdotes. There are lots of reasons that woman in DC suburbs get depressed, both in and out of the workforce. My experience is anecdotal, about 5 or 6 directly and others by hearsay.
