Life expectancy skyrocketed once we discovered and applied hygiene, plus improved sanitation, and also antibiotics. More or less, modern medicine. The industrial era did a lot of things but it also made cities, famous for being horrible places to live in, even worse.

Worker's rights movement also had to spring up for 40 hour work weeks, 2 day weekends, sick leave, unemployment benefits, pensions, disability benefits. Slavery was barely abolished 150 years ago, and it's still present in some places. Ditto for serfdom. Hunter gatherers had healthier diets that settled populations thousands of years after the invention of agriculture. MANY things were better for society and neutral or worst for the average person.
