There is an inverse relationship between income and fertility[1]. If costs were the reason people were having fewer children then why would the poorest people be having more children than the highest earners? It's either we have a very backwards welfare incentive that actually reduces poor women's "independence" or something else is going on. In reality, if you, as a woman, focus on your career until you are 35, implying a higher salary, and then find your fertility has dropped to < 10% of what it was when you were 20 I am sure you start having fewer children.
