Well - there's like another thousands factors that compound this.. Meager examples: - For the last X number of decades it's been beat into the 1st worlds brain that humanity is a scourge on the Earth (climate change - pollution, deforestation, forever chemicals etc). - Common theme among young people that children as just a burden and would get in the way of you "experiencing the world" or "doing the things you really want to do". - Cost of everything seemingly pushed as far as society can take it.

Conditionally speaking, I feel like it's rather hard to be positively disposed to the idea of having children in America.
