Krishna, Are human beings robots without any emotional needs? Perhaps you are one who is fully commercialised and looks at life and everything from a commercial point of view. But marriage is not and cannot be based on money. Marriage is not just for making children or co-habiting. Why co-habit and why have kids in the first place? Lastly, what kind of commitment are you referring to and what for??? Commitment between two robots? And marriage is not a relationship between two families. It is because of interference of family members that there are more and more divorces today.
