Marital relationships aren't meant to be perfect from the start. It just needs two people who are willing to put aside their differences and grow together. That may be a major reason for Finland's declining population, people wait until a relationship is perfect before they commit. Others who cite the rising cost of living as a reason for not having kids are quite right. But the truth is that relationships in our day have become half-hearted. Somebody who's not ready to be committed in a relationship simply cannot dare face the hassels of having and raising a child. Period.
And this is the problem these days I believe. Many people are in their own silo, believing that what they believe, is the right, making everyone else wrong.
Yet, look at what childless people spend, and what they spend it on :)
My wife and I only disagree on the things she's wrong about.
