They aren't people. They are seeds in some woman's womb and if she doesn't want to have it, she should be able to get an abortion. If $ is the reason then maybe your society needs to change. In the last few decades the rich have gotten richer and the middle class poorer. More and more people are choosing not to have kids. I commend them. We're overpopulated. And I'm not having any kids. And if I did I'd pay for them myself.
I made that same choice myself: No marriage and no kids. It cost me several relationships, but I was always an honest and up-front person. The ones that stuck around did it for a challenge. Some women always think they're the special one that will make you change your mind.
On the subject a few months ago I looked up the cost to raise a child today from the day they are born to the day they turn 18. It's $230,000 per child for a middle-class parent(s). That's just raising the child and no college plan. Family of two children? Better have a half-mil for that adventure.
Well, the half-million is worth it for precious kids, right? This is true if you put that money in between your mattresses. But a half-million in a conservative growth account 20 years is pretty hefty sum, and young people today who do their homework on kids opt to have none.
