of course it depends on the parents, but not all the parents are smart enough, especially when they are poor, or blinded by caste, religion nonsenses. In India, many jain gujaratis don't want their children marry from another group. So they push their children to marry only jain gujaratis. Since the jain gujarati population is somewhat low, it can be tough to find a partner, especially if their children are not that desirable by the group. I am not saying arranged marriages are always bad, but it can lead to a disaster as nowadays women are more independent. They have a different mindset than village women. They can make reckless decisions thinking it breaks their chains, but it eventually leads them to their demise. Not all the guys are same. Some guys won't accept a girl back once she left him.
