O_G, I wasn't talking about tragedy necessarily, as I'm sure you're aware, the bond of marriage isn't as strong as many feel it should be, and I agree that when it's an act of selfish desire, especially when it's worked around a womans career, as if to say 'I've done what I wanted, I quite fancy a baby now' then there are serious moral issues there, but as we know the standard family of 2.4 children isn't the only way to raise a child, there are plenty of single mothers who raise kids on their own far better than a classic model of a happily married man and woman. I'm simply saying I don't think they should rely on a married couple - yes, single woman - no way of deciding.
That said, if it's all done privately, money talks and are morals going to come into it?
Regarding your point on over-population, although I believe it is a potential issue, and I may be being naive, but limiting the amount of children in a family should be the choice of the parents alone, what they can / cannot handle, what they want. Of course those living of handouts are a burden, but there are plenty that just work harder to support their family. China and India have encountered their own problems with limiting offspring.
