Yep, Metatron, if all JWs took a good look around and saw the "youth drain" in action, it might change some of their attitudes.
Of the kids I grew up with, at adulthood:
P* family (two boys, one girl)--one boy still in
R* family (one boy, one girl)--no kids in
W* family (one boy, one girl)--girl still in
M* family (two girls)--both in
W2* family (two boys, four girls)--one boy and three girls in
H* family (one boy, four girls)--no kids in
H2* family (two boys)--no kids in
I* family (four girls)--one girl in
S* family (one boy, one girl)--no kids in
C* family (one boy, three girls)--no kids in
W3* family (two boys, one girl)--no kids in
my family (two boys, one girl)--no kids in
So, a congregation that had 38 kids in it when I was a child ended up with 9 still JWs as adults. According to my math, that's less than 25% retention--and at least two of those women still in (my cousins) would leave if it weren't for their husbands.
Of course, I'm math impaired. I'm sure the Borg can work it out to some sort of glorious increase.

Edited to add: I don't think the JWs will take a good look around, because those in my parents' generation can't bear it. I know my mother thinks we left because of her failure as a parent, and not because of the organization's failure to provide any kind of spiritual "nourishment."
Also, I think it's important to note that, in all of those cases where kids have left, there are now incredible stresses on the family structure: situations where parents are shunning kids, siblings are shunning siblings, and, in at least one situation, a woman was barred from attending her grandmother's funeral. Frankly, it sucks.
