    Fractional reserve banking (creating money out of thin air) enabled investments in housing, research, and more education for ordinary people. Some things that we don't think twice about made a huge difference. The mattress. Washing your hands with soap to not pass on germs. Life-expectancy worldwide would have grown even more if we had gotten rid of tobacco-smoking and would have fed everybody (there's food for 12 billion....)

    Antibiotics and vaccinations account for most of it. Better nutrition, better medical care that's far more widely available, understanding of transmission of disease by more people, basic sanitary practices around food, comprehension of clean water and sewage practices...

    Medicine has got better and evolved, their's now so much more research been done to various illnesses like cancer etc.

    Years ago a lot of people died from things like Tuberculosis etc, which you can now get a basic jab for now.

    People are eating a lot more healthily as well, so people aren't getting diseases like scurvy etc.
