“What many contributing factors have changed?”
To name a few: age of chosson, age of kallah, the expectation that money shouldn’t play a role, childbirth mortality, arranged marriages (related to age).
Since 30 years ago… how much has the age of the Choson gone up? How is money more of a role today? How are arranged marriages different now from then?
Is it realistic to go back to how it was done 30 years ago? Is it a good idea to do so?
