Death rates fall faster than birth rates:

These people simply didn't know how many of their children are going to survive.

1. humans aren't produced in response to job market demand

2. even if they were, they have a huge time to market (at least a decade), which leads to feast/famine situations as supply/demand lags and fails to match demand/supply. You also see this other industries, eg. semiconductor manufacturing. It takes a lot of money and time to set up a fab, so they'll keep pumping out NAND/DRAM chips even when the market is drowning with it, just so they can recoup their investment.

It'll continue as long as there's an abundance of cheap food

Right, because food is unafforably expensive in rich countries with low birth rates.
