I think that there aren´t many advantages in arranged marriages. The only advantage would be that even if the person didn´t find the other pretty or clever or sensitive, he can be attracted by money and get a good life with it .
But if the person he marries doesn´t have money ,then it´s not possible.
Arranged marriages is only the family of the husband, especially in India where they receive money from the family of the wife that has got to pay to marry its own girl . And I find that really immoral that somebody can act like that because it´s the reason of important adulterates of woman in this country, it´s sad to have to spend all your life with somebody that you´re obliged to stand everyday, most of the women can´t do it.
Arranged marriages are definitely a bad thing.
