Writersoul, you don’t know what’s the cause and what’s the effect- and that’s what I think is the problem with NASI, not so much that they’re necessarily WRONG (they may well be right for all I know) but that they think theirs is the ONLY right answer, which locks out so many other possibilities.
It doesn’t have to be the only answer. If they’re right, than aside from whatever else ails our society, the numbers issue must be addressed if the issue is to be resolved.
I’m not sure why they haven’t stressed this, but their being correct is not only based on anecdotal evidence of more single girls than boys. Even if I would have no observation of how many older singles there are and the disparity, just knowing that there’s a gap and population growth would predict such a disparity. Of course, one can argue that there’s no gap, and that we don’t typically have large families and a growing population, because there are no studies. At some point, though, it just becomes ridiculous to deny the obvious.
