Boedhi Adhitya, thank you once again for shedding light and answering questions that others seem unable to answer. I have found your input on both this thread and the forum in general to be invaluable.
Purwacarita, i am not sure where you have gotten you ideas about marriage "under capitalism", but i can assure you that at least here in the USA the average couple still marries for love of one another, not money or possessions. What ever gave you the impression that "it's quite different in capitalistic situation where marriage concerns financial achievement of the groom." Gee, if that were the case i would never have been able to find my beautiful, loving wife.
Yes, there are certainly cultural differences between here and Indonesia, but i am concerned that you seem determined to push forth the differences you perceive rather than the similarities. Like many North Americans my wife and i began our marriage with love and commitment to walk the path of life together...and very little else. I think perhaps you have watched too many episodes of "Desperate Housewives" or some such TV show.
Fortunately, even so called reality television does not reflect the actual lives of real people.
