> Don't rationalize it with clichés like "love is all that matters"

Counter data point. My wife is Argentinian.

I'd say the values you see in her family primarily is "love does come first" and strict boundaries on kids. E.g. the adults are talking, go away.

When I compare that to my own nieces and nephews, they have little boundaries, are quite lethargic and can be quite arrogant. Yet their parents would all describe themselves by your standards.

We also tend to put our elderly in homes, an idea that is abhorrant to my wife.

So I guess what I'm trying to say is ideals are nice. But it's purely theory, mostly to serve your own sensibilities.
