I'm seeing a lot of this in my extended family. If society isn't telling you that you have a primary role in creating and supporting a family, and that you're necessary for the future of society itself, it turns out that you need a lot less money to survive, and you have a lot more time on your hands.
I'm part of the problem I suppose, in so much as one can call it a problem. I gave up dating a decade ago because being in a relationship was not necessary for my life goals and dating was a pain in the ass, plan to semi-retire early with a relatively minimalist lifestyle and part time job, etc.
When you don't have someone to spend your money to keep up with the Joneses you suddenly need a lot less: less space, less home decoration, less clothes, less going out for food, a smaller ride.
Yep, you "need" a lot less money when you don't have someone insisting that you buy her a diamond ring, a BMW, designer clothes, a big house, maid service, give 10% of your income to some church, etc.
