Learned a bit about this in anthropology. It's pretty old school in my opinion and not really something I'd want.
Pretty sure arranged marriages are between 2 families with a relationship.
It's very common to see a marriage as 2 families being married and not just 2 individuals.
Especially in cultures where family is very important, which no offense, american families have little to no importance compared to other cultures.
Also, family based cultures take big notice on the parents of whom one is going to marry regardless of arrangements.
Not sure if many americans pay attention to this or if it even applies.
American families tend to be so disconnected that it leads me to believe it doesnt apply as heavily, and just because an individual comes from a good family it wont be a good indicator that the person is suitable, and thats where the strong-family-influenced-culture will step in to help.
But then you hear that talk about the forced arranged marriages and people being sad, which I think are mainly just for movies.
I'm pretty sure most arranged marriages arent crazily cynical like the movies, but no doubt it happens just like child actors and parent scandals.
And like already mentioned in this thread, people would work on their marriages much harder, not only other cultures but even older times in america.
Just a different mind set back then. The same mind set that caused families to have many children.
