Look at https://ourworldindata.org/economic-growth and take 5 minutes to look at the data on the rest of the site and you will understand how much life has improved not just in raw numbers (there are more people living above the poverty line than existed 100 years ago), but more importantly in percentage terms - a far smaller fraction of people live in poverty today than in 1880.

In fact, the number last time I ran it was that less people live in abject poverty in 2019 than did so in 1880 - despite a 7-8 fold increase in population.
