Because our entire culture revolves around getting married and having a small legion of children.
You're valued based on your wealth, job, and the number of offspring. And of course, wives are mere objects, an asset. There's a reason everyone wants a "ڈاکٹر بہو". Doesn't matter if her role will be limited to a housewife, producing babies on a yearly basis.
Gotta have a trophy wife.
And if she turns out to be infertile then... well, too bad! She's no value as a person.
Frankly, I wish I get an infertile wife or at least a vasectomy or something. I just don't want to raise a bunch of little poop factories. Raising children is a lot of work and, honestly, I don't want to give up my carefree lifestyle where I can afford pretty much anything I want.
Am I being selfish? Possibly. Do I give a sh!t? Not in the slightest.
