No, it is more like feudal-Europe levels. There is no precedent in US history for the levels of inequality we are seeing today. The Gilded Age was actually far more egalitarian.
I wonder in how far the manufacturing knowledge distribution played a role there in the later medieval period.
We have now for the bulk of our basic needs very mature manufacturing chains where most of the needed knowledge is integrated in the machinery, the recipes/programs, the expeert systems.
In the late medieval period most of the manufacturing knowledge, the craftmanship, was in the human labor.
Which delivered such a power to the craftsmen, and their guilds, that the land/peasant power structure eroded in overall importance, and nobility had to give more and more freedoms to those citizens.
In todays world employees working in higher employee knowledge sectors, up to innovative edge do earn much more than operators of mature machinery (people feeding machines or in logistics, the junk labor, getting junk wages).
Reducing the power of the bulk of the employees to a consumers and voters power, but no longer essential elements in the manufacturing (or services) based on their needed knowledge.
This is an ongoing process with future AI, robotising and mechanisation.
Capital more an intermediate medium.
