Just thought I would point out that gender-related socioeconomic phenomena usually have a more complex explanation than "it's absurd". This is also true in the West, with all of our weird dating customs. But it's harder to see the absurdities you are taught from birth. For example, why is it traditionally (and most commonly even today) the guy's responsibility to take the initiative in the courtship process? This article provides a stark alternative which is a very efficient counter-example to the evo-psych explanations a lot of people come up with.

I'm not advocating cultural relativism; the reality described in this article sounds really shitty, but it is usually instructive to go deeper and ask why things are this way among poor people in India. With sexual attraction being one of the most powerful drives and varying socioeconomic conditions in the world, it stands to reason that different places will have wildly differing customs. These change over generations, as the conditions that formed them change. For instance, an undersupply of men in the wake of a deadly war could be one force which vastly increases the sexual market value of men, and causes customs like the ones described in this article.

Look at China if you want to see a third way this can play out, where the roles are reversed.
