Do you want kids?

Germany is facing declining birthrates. It's a trend in most Industrial countries. So what motivates you to have/not have kids? I sometimes heard that it has to do with financial difficulties but I personally don't believe this is the reason people don't have kids. I think most people see it as a newer lifestyle choice that hasn't really been considered as much in past generations So what are your thoughts?

Edit: I guess I was wrong in my assumption that it is mostly a lifestyle choice. But I'm not judging anyone, just curious about the discussion!
