There used to be some truth to that but not so much anymore. It's historically correct that the poor used to have more kids (and I think are still a bit more likely to have them than the middle class). But what started to happen about 10-15 years ago was that everyone became less likely to start a family except for rich people. To be precise if a woman is rich enough to afford childcare she's much more likely to have kids.

Here's an article on the topic: https://www.theguardian.com/lifeandstyle/2014/oct/25/women-w... - that's about a decade old and the evidence/trend has only grown.

Children are just another one of those things that is increasingly out of reach for the American middle class, along with property ownership, health care etc. For the poster I responded to to ignore the economic data and paint the middle class and ordinary human beings as being selfish and immoral is perverse.
