Hmm, I dunno, does the irresponsibility of one group of people translate to increased burden for those who have no influence over them? I would think not, otherwise it seems we should abstain from eating until all those in Somalia and Ethiopia are fed.

I see no immorality in wanting to preserve one's lineage if legally possible. The fact that economics plays a role shouldn't necessarily make it immoral either, lots of kids are orphans due to economic circumstances.

I guess it depends on your convictions. From my perspective, it is far more immoral for anyone to bring a child into this world whom the parent(s) cannot adequately care for, which is far, far more pervasive than this.
