I agree and disagree. I'm certainly not arguing that industrialization isn't miraculous. Even from a parenting perspective, I think most would rather raise their kids in a stressful nuclear family than watch half of them die from preventable diseases. If you read about the anthropology of childrearing it's filled with endless heartbreaking accounts of parents having to make choices about letting one kid die to focus their resources on more viable children.
But the point I do want to make is that our physiology and psychology is largely fine tuned by evolution for a certain operating environment. When we step outside that environment, it often introduces dysfunction in unpredictable ways.
An extreme example: as land animals we wouldn't survive very long at the bottom of the sea. More prosaic example: it's undeniable an environment with many more and tastier calories creates chronic health problems. Metabolic disease is virtually unknown in hunter-gatherers.
A rough heuristic is that removing purely adversarial elements from the evolutionary environment produces an improvements. Pathogens, predators, physical injuries, birth-related traumas, and famine. Removing or mitigating those elements are the main reason life expectancies have improved relative to hunter-gathers. But once you step outside the totally hostile elements, most environmental changes tend to be neutral at best and harmful at worst. Physiology and psychology rely on delicately tuned equilibria, which are easy to disrupt. The consequences aren't terrible, but do tend to subtly accumulate over time. Hunter-gathers die fast because they get a concussion and bleed out. Westerners die slow from the accumulation of plaque in their arteries.
