I have been lurking in the trend for a while now, and I just want to ask if someone can give a summary:
1 why is there a general low desire to have children in well developed economies?
Families tend to want their children to live in a similar or better position than themselves. In other words, for their children have sufficient skills to at least be competitive with their peers.
Undeveloped economies tend to lack the capital accumulation needed to invest in labor-saving machines as well the skills needed to make machines more cost-effective than unskilled labor. The resulting economies' focus on unskilled labor means the amount of education required for children to be competitive with their peers is minimal and so children both require much less investment and have significantly shorter payback periods. Even children not out of elementary school can be useful and profitable in an undeveloped economy.
In general, children take so much capital and take so long to start initial revenue in developed economies, that it's outside the scope of cognition for most people. Doing something that will turn a profit in 8-10 years is still in the realm of consideration for most people. Doing something that will turn a profit in 30-40 years is not.
No country has moved in large enough steps to counteract the large costs involved in raising competitive children.2 following on is there any developed country in the world that has successfully counter acted this low desire and boosted indigenous population?
Let's take some US stats, runs some math, and look at the magnitudes we're talking about.
In 2017, USDA says a middle-income married couple may spend $233,610 ($284,570 with projected inflation) to raise a child born in 2015 to the age of 17. According to Community College Review, in-state public community colleges cost an average of $4,722 per year. So we're looking at 250-300k USD to raise a minimally-competitive child.
Median income for a middle-class two-person household is around 72k USD. Savings rates on disposable income in the USA averaged around 8% pre-pandemic (5.1% now). There should be approximate 7-8k in taxes from federal and state combined, so that's a savings of around 5.2k per year.
250k-300k to raise a child vs saving 5.2k per year - it's not possible without offloading that debt. US fertility rate is at 1.7 which isn't much better than China and is still declining.
Instead the US has relied on dual crutches of illegal immigration (foreign-born Hispanic mothers being the driver behind much of the growth in the last two decades) and regional segregation. Rural southerners are quite poor and have much higher birth rates for example. But look at the 1.7 TFR and declining trend, it's obviously not enough.
Take a look at the measure South Korea politician floated before getting shot down by their President. That was just a $26,800 LOAN and it was still too much for their government to contemplate. Governments are still just pussyfooting around these fertility problems.
US births per year is something like 3.6-3.7 million, so we're looking at something like 1-1.1 trillion dollars of eventual costs per year. That's 5% of the US's GDP. No one is spending even close to a fraction of a % of their GDP on solving these costs so of course no country has successfully dealt with the issue.
