It's not about an objective level of means, but more about one's relative standing and its security.
Take a modern young couple in a place like NYC. Having to work incredibly hard in an uncertain job - both of them - never too far from being unable to pay rent (or mortgage, although that now tends to come later in life). Meanwhile bombarded by ads of all kinds (and people they see around, both in real life and online) to have consumption of a certain level just to maintain the status quo of their social standing.
Add to that a complete lack of positive vision for the 'developed' world but plenty of negative ones. A complete lack of any sort of utopian thinking. Including the fact that whoever does end up having children will end up with those children later having to support all the pensioners.

So in a way, the poor are more secure in their poverty than the young people in the middle, and therefore they procreate. So do the more wealthy that are secure in their wealth.
