To be fair, some improvements have been made, even at the feet of these giants, driven by government action and populist initiatives. This has been at the cost of concentration and increases in pollution and poverty in the poorest nations. The future looks bleak today, as the divide grows and progressive progress has all but halted.
Poverty is way down globally. Poor nations are far from where they need to be, but we've lifted a billion or so people out of abject poverty in my lifetime.
Don't let a determination to believe everything is bad force you to ignore when things get better.
A decrease in poverty in this case though is traded by an increased addiction to what the oligarch provides. Is an entire society in a dystopia that provides the basic physical comforts but strips us of meaning in life a good end? I think not.
