The thing is, the US has clearly gotten way better in the past 50+ years, while the past 30 years is maybe debatable. But if we're looking at past 30 years globally, there's no sane way to argue it hasn't gotten way. It's been an absolutely amazing past few decades in terms of reducing global poverty. We've seen something like a billion people lifted out of poverty—child mortality, clean drinking water, education, basic nutrition. We've a long ways to go, but if you're argument rests on ignoring over a billion people having their lives transformed in this way, I'm not sure you're on the side of the poor.
