but the difference now is that rich people are so unfathomably rich...Compared to when? How many times in history has wealth been less concentrated?
As far as I'm aware, for almost all of history post-agriculture, wealth was highly concentrated while the average person lived in abject poverty (think: kings vs peasants). The mid-20th century was an era of mass prosperity in the US and parts of Europe, but it was an anomalous few decades, not the norm.
