For one, it keeps a couple invested in something that isn't themselves or work. It's natural that a couple should want to strive for something together, like raising their children into adulthood, and having children is the primary thing that is biologically codified for this. I thought I didn't want kids, then I realized I don't find work especially gratifying, and I heard lots of really interesting things from people who do have kids about how important and meaningful having them is to them; I'll find out soon enough. In hindsight, I was disturbed by how having kids worked out for many people around me, and I was afraid that I would make the same mistakes. I know that this doesn't have to be the case. Maybe some people feel the same way about work, and maybe some couples work together. Maybe striving towards financial goals or living situations does the trick for other couples.
