While this argument makes intuitive/emotional sense, it's not the case that humans start having more kids once they can finally "chill t f out"—though I totally understand where you're coming from.
In practice, populations in actual hypercompetitive hellholes, where they're not just competing for a job/status/basic financial solvency, but literally for their food security, physical safety, etc., are those which are having more kids.
The pretty-much-universal trend appears to be that once people become more educated and comfortable, they stop having kids above repopulation rate.
All that said, we are not arguing in favor of making life more stressful for any group, be they in developed nations or nations facing severe hardship. We're simply pointing out that "make raising kids cheaper/easier" and "make life easier" are not interventions proven to boost birth rates.
