Distance is more than geography

In strategy class we had a chapter talking about "distance" between countries - in term of operating business. I and some friends found a lot of business "frameworks" and models apply so well in other issues, say, finding and assessing a dating partner. If you relate them well, they will work wonders for you.
Here's this one: my funny interpretations of the CAGE analysis.

Cultural:
I would say this is the one of most important things in a romantic relationship. Culture determines language, religion, values, all of which are important. Romantic stories cross language, culture, even religion boundaries sometimes appear. Yes they sound cool. But very few end up together, and many such couples end up divorced, saying "We really can't get along..." Anyway, it's way easier to find a soulmate among those who share the same culture with you.

Administrative:
Well, it's a bit hard to apply this one here. But there ARE administrative barriers involved, for example, parents.
Think about Romeo and Juliet, you will understand this, right? Today in some places - Asian countries for instance - senior family members are still key decision-makers and stakeholders of your dating or marrying someone.

Geographic? or Genetic...
I'm not particularly interested in talking about geographic distance. Instead, one thing I found common is people have expectations on the other person's physical characteristics, especially height. Part of the reason is physical attraction, and you are afraid of losing face if found dating with someone unattractive. The other part of the reason is for the sake of next generation - in choosing a marriage partner, you are looking for better genes.

Economic
Well, money speaks, whether you believe it or not. Yesterday I read an interesting argument: gender equality enlarges the imbalance between the rich and the poor. How come? Because people generally choose a partner with similar level of education, skills, experience, and essentially INCOME. As more women join labor force, the distance between rich and poor families are doubled. This is an unintended outcome of gender equalization.
