This fact makes the high levels of singledom in recent years even more remarkable and concerning. Even with strong economic incentives, a large fraction of people really don't want to pair up.
Forget being single, having a housemate/roommate is so painful that I refused to have one once I was in my late 20s. I’d rather pay a fat chunk of my salary to the landlord than have to deal with someone who created a mold problem by running a humidifier 24x7 because they wanted better skin.
What if the higher levels of pairing up was due to even stronger economic incentives in the past, specifically for women?
> a large fraction of people really don't want to pair up.
Don't want to pair up, or can't meet/find someone with which to pair up?
Because from your massive oversimplification, you're making it sound like everyone has 50 potential partners knocking on their door daily asking to hook up or get married, and they tell them to get lost so he/she can keep play videogames in peace.
Have you asked single people why they're single to better understand the issue? I think you'll find that most people actually WANT some sort of loving partner in their lives. Otherwise the pet industry wouldn't be so massive in the west if people were so happy living alone without any company.
