Are global averages meaningful to look at, though? You could have millions lifted out of poverty in countries that are becoming more developed, counterbalancing changes elsewhere, without neoliberal policies being correlated.

In Brazil, extreme poverty was reduced by 75% during a decade of a left-wing, welfare focused government, and then promptly went up again as soon as neoliberal (not exactly, but close enough for the purpose of this argument) politicians came back to power. And the averages didn’t improve either - quality of life has deteriorated for everyone else too.
