Birth rates in the first and second world have plummeted because the economics are disadvantaged to the point that most of the pipeline needed to create children has been shuttered. Agency has been stripped, and psychological differences in gender have been exploited towards a for-profit business model where there will be no children. Its the same thing the USDA uses in combating the screw-worm, but we call it online dating. If you only match up against people you aren't compatible with long term, you never get to the stage where you couple up and have children. Part of that is also financial security, and there is a biological wall where after a time you can't have children.

The concentration of production today has become one-sided, and lacks the ability for economic calculation. Price discovery for example has completely failed in a number of markets as a result of dark pools, and sieving of business into fewer hands through non-reserve debt issuance is occurring gradually but surely.

The socialist calculation problem defined by Mises seems to be occurring, few have noticed yet because the problem by definition is chaos with no differentiating features aside from the overall volume of chaos growing.

Statistics also really can't tell you anything about chaotic environments (stochastic environments). Islands of consistency within the 3-body problem as an example for the literature that applies.
