I've been watching the American strain of this play out for a few years now.
The conservatives as they are wont are very much into the notion that everybody gets married and that sorts out a big proportion of the societal issues.
But they also don't want to help couples get married in any tangible financial sense and are then perplexed as to why people with fuck all money are so reticent to fall into the marriage trap.
You're right though, a strong relationship will withstand (almost) anything.
