The last time income concentration in the US looked like this was around 1900. That generated the union movement and interest in socialism and communism.

(This time we got Trump. Oops.)

A lot of people forget that fascism had an overtly anti-capitalist attitude, espoused in propaganda and racial imagery (take a look at what a factory boss looked like in Nazi propaganda and you'll understand what I'm trying to say). And a program, too, that of subservience to the State. However, I'm not saying it wasn't capitalistic in effect, or anything like that.

Only that a system breakdown leads people to seek out extremes. In the late 19th and early 20th century there were ideologies in Europe and the U.S. that were available to cling on to, whether you were a union member, a soldier returned from a devastating war, or a deeply religious person, something was there to explain the order.

Today we have Facebook news (60%, is it, of Americans get their news primarily from there?). We have programmatic advertising, a feedback loop of information being sent to our attention and our behaviors being tracked and sending back datapoints for further optimized tracking... I'm not sure what this says about the state of ideology and the tremendous disunity in western society compared to 100 years ago, in the sense of people coming together under the banner of coherent ideas... But it'd make an interesting thesis paper.

That's nothing compared to the income concentration in Old Kingdom Egypt.

Those who cannot remember the past are condemned to repeat it.
