Wealth generation has been growing exponentially for 200, 300 years. Maybe longer. Noting that people in the past had less wealth than today is hardly a point. Anything but the most jaw-droppingly stupid economic systems would have todays population being very wealthy compared to those of yesteryear. Even the experiments in authoritarianism and communism have managed that although they killed a lot of people along the way.
And I find it a bit of an eye roll that the minute the gold standard comes up all the "inequality is out of control now!" people fade into the background and the "back then, everyone was poor except the wealthy" arguments come to the fore. There is an inconsistency in the hive mind. This is a system where we print money and give it to the asset owners. It is visibly stupid.
