You don't have children so they can take care of you when you're old. Do you?
Besides, who's to say they won't die before you do?
Who's to say they won't develop some kind of disease or get hurt terribly in an accident and you won't have to take care of *them*?
I feel sorry for who plan their old age around "who's going to take care of me"? Very leftist viewpoint when you think about it.
What a silly response. Extended families have been around since the beginning of time, and its only been the last few generations where we began shuttling parents off to old folks homes (though certainly sometimes for medical reasons that is the best choice.) Nothing leftist at all about the concept of taking care of your own family.
Each person has to make their own moral decisions, and I'm not going to second guess them, but one of the benefits of extended families has always been that those who cared for their children for 18 years would in turn be taken care of when they could no longer care for themselves. That isn't asking gov't to do so, that is a family taking care of their own responsibilities. Some may have lost sight of that, for whatever reasons, but it is something to consider.
