I agree it would be difficult to get many people in today's world, especially in places like America, to agree to an arranged marriage. The mind set that was once in place no longer exists. We no longer think of marriage as a means of procreation and carrying on a family or monetary line. There are no longer dowries or other such fiscal gains to be obtained by marriage. Therefore, societal opinions about marriage have changed.
Frankly, there is not a social foundation for arranged marriages, which usually flourish in societies where the transmission of property, especially land, is of paramount importance. In western societies, the cultural practice of arranged marriages often was accompanied by laws such as coverture, primogeniture, and entail, which basically dictated that men could acquire property through marriage and pass it down through their family line. None of these things are intact anymore, and this, along with the commitment to individual free will that is now so much a part of western society, make arranged marriages both undesirable and frankly not needed.
We would be a much less individualistic society. If we accepted arranged marriages, we would not be thinking about things like romantic love and personal fulfillment. Instead, we would be thinking about duty to our family. This would be a major change from our current mindset.
There are not many people in today's world (at least in America) who would even consider accepting an arranged marriage. We are so used to having things exactly the way we want them, from burgers to cars, that the thought of someone else choosing just about anything for us is rather unacceptable. To that extent, it does not seem as if arranged marriages will ever be the norm. If, however, everyone took the concept seriously and parents really sought out good matches for their children based on their temperaments and other important attributes (NOT just money or politics or other relatively superficial things) and the children were willing to respect their parents' wishes, it might be that there would be a greater level of commitment to the marriage and less inclination to just abandon the marriage when things get difficult.
