Some of you white folk are a lot more narrow minded than you think. Arranged marriages are probably one of the most thorough and solidifying methods of finding a spouse. If the guy and girl in question click on meeting each other and find each other's personalities compatible then both families get involved and provide some sort of relationship security through their involvement.
One of the great benefits of getting an arranged marriage is usually two people are put together based on them having equally desirable characteristics and that usually helps the longevity of the relationship, even things such as female and male disparity in mortality is considered where the women are usually slightly younger.
Western/ love marriages are usually based on emotional decisions made by people younger than 35 and occasionally you end up seeing the odd mismatch. The idea of being romantically involved with multiple people before you find your true soulmate also means there's plenty of space for mixing casual with serious relationships. While there may be some benefits most are overrated as many married couples realise the burden of expectation from a "love" marriage are almost impossible to live upto, on the otherhand the unknown of a arranged marriage leaves some space to breath, find your feet and adjust your expectations for a realistic future which almost always involves some level of compromise regardless of how much 2 people love each other.
