But in the past 4 decades, I'll remind you that around 800,000,000 Chinese (that's eight hundred million people) were lifted above the global poverty line and were able to stop subsistence farming. https://www.worldbank.org/en/news/press-release/2022/04/01/l...
So to say that global inequality is getting worse, when billion+ have been lifted out of abject poverty in that time, it's not correct to me. Things were worse 40 years ago when billion+ more humans were below the global poverty line, even if today billionaires are even richer than the middle class.
Imagine you live in a neighbourhood of 50 people. Everyone starts earning more, that's absolute income increase. Then imagine your richer neighbours income has increased 100x faster than anyone else, that's income inequality.
