I don't think you understand the economic and quality of life decline experienced the generation that is now 30-40yo.
There may be places where worst economies, but the rate of changes counts as well. The middle and lower class were at least 3-4x better off 20 years ago than what they are today.
You're wrong, it has to do with culture. Very little is effected by economics.
It reminds me a lot like hobbies people associate with rich people, like traveling.
If traveling is a real hobby for you, you will find a way to do it even if you're poor like I did when I was young. For me it was through mistake airfare scanners and hostels, but some very poor 3rd world people literally just walk / bike around the world. Sleep in tents, and pan handle / or do some odd jobs for food money.
Then you'd see higher fertility among the upper class, who have it about as well as the middle class had back then. You don't though.
It's just the excuse you use for something you don't understand about yourself. Go talk to the r/childfree crowd, ask them if they'd ever do it for any amount of money. They won't, and neither would you. They at least understand themselves a little.
