Yes… and someone to their liking has the possibility to be a more stable, longer lasting relationship. Plus, they’ll come with a stronger support network.
So if you think of a marriage as being to promote stability and perpetuate humanity, arranged marriages make sense. If you think of a marriage as something based solely on romance, the experts are obviously the people getting married.
Personally, what I’ve seen in western society is that people tend to live common law, and when a couple feels like they’re fairly stable together and they want to have children, then they get married.
This obviously doesn’t work in a society where you don’t get to try out living with someone first, or where birth control is frowned upon.
