Earlier quoted context omitted.
Declining birth rate is not actually a problem? OK then. Also, referring to children as "financial drains" makes them look much worse than they really are. I wonder if you've ever had children..
Yes, and we've stopped at one because children are a financial drain. As an example: if we both continue to work, weekday childcare will consume 70% of my wife's income. Add to that all the other costs of raising children, and the potential income lost through not being able to take advantage of new opportunities as they arise, and I understand the Danish situation.
Where I'm from, things are different. It's the responsibility of the children to take care of their parents, especially during old age. In some cases, all of the children decide to live with their parents along with their families. I know it sounds weird, but it works in practice. This, I believe, makes raising children worthwhile, because there is a chance, even if it isn't that large, that your children will return the favor when you become old.
Sorry for the long rant by the way. I wish you and your wife good luck :)
