I read your link. Did you watch the videos? The criticisms in the paper you linked accurately state things like GDP != poverty and the best measures start in 1981. There are many ways to measure things. Yes, we are missing good data. But we have others and all the data aligns. People are doing better. In the videos, they are about life expectancy, child mortality, average income, and gdp. Things are looking better all the time.
Yes, bad things are happening. But the trends are in the right direction.
