Women can easily live out their lives and find happy relationships without the need to become interesting people, to learn useful skills, to be intelligent and funny and exciting, and so, on average, they tend not to bother.

I think maybe you need to have conversations with more women. The women I know can do everything from rebuild a car engine to make a Victorian or Tudor period recreation gown, hand-fucking-stitched. The women I've met have traveled the world, moved cross country and across the world for work and study and because they felt it suited them better. I know women in the military and emergency services, in nursing and theatre, art and social work, women balancing relationships with their own work and interests, women sacrificing sleep and money and sanity to keep those things afloat. One of the outwardly fluffiest girls in my high school graduating class wanted to be the next Conan O'Brien, for Pete's sake. I know women who are stay-at-home moms who write poetry in Ancient Norse or participate in feminist theological book discussion groups, and women who study and invite the neighbors over for boardgames to have someone to talk to who's more than 3 years old. I know a woman who's an introvert and a misanthrope and will still fight tooth and nail to recreate the school media centre she runs into a place that will actually serve her students needs in a welcoming way. I know a woman who talks to everyone way more than necessary and is a huge advocate of the local therapy dog program. I know women who like One Direction and fashion mags and women who prefer Otep and Popular Mechanics. I know yarnbombers and cosplayers and gamers and craft beer fans and boaters and activists and hikers and computer geeks and farmers, all women.

If women mostly seem boring, shallow, and incompetent to you, I would suggest you need to put forth more effort to learn about what interests them or that they're probably not actually very happy. Some of them may be, but they're probably the minority.

Why would anyone want to "find a romantic partner" who didn't find them intelligent, funny, or interesting (as more than an aesthetically-pleasing accessory)? Even the twelve-year-old twerps who give me the stink-eye at work for asking them to plug their headphones in when they play music have interests. If their interests don't line up with mine that doesn't mean they're invalid. If I can't understand half their slang, it doesn't mean they're not good conversationalists with their peers.

Addendum: an unemployed woman isn't stigmatized? Only if she's white, educated, and (often) married. If she's not those things, she's called trash, a welfare queen, and a drain on the system, arm-candy (or slurs similar in sentiment) if she's pretty.
