Why Do Arranged Marriages Work?

I am a hard core believer of a significant correlation between love and marriage. Any deviation from the above path by default or by choice leads to unhappy, unprecedented circumstances or instance which leads to separating the word 'love' from marriage!

Now that's an observed trend and extensively marketed concept in most society, novels, stories and films. I do not want to argue whether the above statement is correct or false but would like to think or rather note down, why I am coming to realize 'Why Arranged Marriages Work' ? So here are my takes (note - my interpretation is entirely biased towards the eastern/Indian society) : -

1. In an arranged marriage usually both the families are excited about the binding of two families instead of the usual observed trend of unwilling ties or compromises made at the family level when the mates choose themselves.

2. The excitement creates lot of positive and optimistic energy at the family level which flows down to smaller subsections and eventually accumulates with the mates who are getting married.

3. In most cases, in an arranged marriage, both the players are interested in getting married, are willing to move ahead in life, are wanting to start a new chapter. This brings them on the same platform as well. Solving any equation of life is easier if both the variables are integers, fraction or real numbers ! The willingness to get bonded by both the variables is an essential criteria here and the main reason behind why marriages work, be it self arranged or socially arranged :) . In late or arranged marriages it is observed more frequently than otherwise.
