I used to think that but it turns out that arranged marriages are quite successful: http://www.statisticbrain.com/arranged-marriage-statistics/

Obvious it's not as simple as comparing the divorce rate of love vs arranged marriages, cultural factors play a huge part but from what I've seen in India the fact that they're committed to making it work seems to make for happy couples.

Most people consider love what is better described as lust: a psychological attraction that lasts for about 2 years. If this is all you have to base a relationship on, then after 2 years the feeling wears off and the whole relationship is done.

By contrast, if your relationship is based on just about anything else, whatever those other things are are not as likely to change and so the basis of the relationship doesn't change either.

Parent comment was suggesting less attention given to physical attraction and more to other forms of attraction (personality, intelligence, SES, etc.), not that all forms of attraction were ignored.

I would think it would be just the opposite or least if there were financial incentive ok. You fall in and out of love all the time, or at least I do.

"Particularly" is ill defined here -- as is "attraction." Some aspects of attraction will go away over time (most obviously looks), others vary from time to time. What matters is the ability to love the partner even when you don't like them at a specific moment in time -- because those moments aren't the eternity.
