Sounds good, except that fertility rate correlates inversely with income. https://en.wikipedia.org/wiki/Income_and_fertility

If you gave a population a $10k raise (in a hypothetical world with no inflation) the birth rate would probably DECREASE

> Two recent studies in the United States show, that in some circumstances, families whose income has increased will have more children.

There's a massive gulch between "too poor to have ubiquitous access to birth control and healthcare" and "rich enough to provide the upbringing I desire for my child". Most Americans exist in that gulch.

> But something happened to the American family over the last three decades: that downward slope became a U-turn. Women in families in the top half of the income spectrum are having more kids than their similar-earning counterparts did 20 years ago. Women from the very richest households are now having more children than those less-well off.

Give people enough resources and they'll have more kids. But it takes a lot of resources, and an increasing amount year by year, to hit that mark.

>>Give people enough resources and they'll have more kids.

Not sure I buy that - I know plenty of couples, each of them with good 6 figure salaries, who have no interest in having kids, ever - if they had 7 figure salaries, I don't think it would change their mind one bit.

Right, low income causes kids, so what we need are more poors! We don't enact regressive policies because we want money, we only do it because we love you!

It couldn't possibly be that the causal arrow points in the other direction, that kids are an economic burden, cause hardship in an already economically strained population, and those who escape do so in part because they choose not to have kids. Nah, couldn't be.

Being economically strained is relative. Middle class people clutch their pearls at the thought of having children before they have completed their master's degree, have their 4 bedroom house in a safe neighborhood with good schools, maxed out retirement accounts, and a membership to Whole Foods. Broke people have a different idea of what necessities are so they have no problem pumping out kids.

This is not totally correct. One reason it appears that fertility is inversely correlated with income is hidden confounding variables. Among comparable populations (within the same country, as a starting point) income is positively related to income.

Wealthy nations have easier access to contraceptives and low child mortality, and women joined the workforce. It's not so cut and dry as a mere question of income. Even your source has a section for contrary findings and fertility j-curve when using HDI rather than GDP.
