I sadly think if the promise of AI happens this is the likely economic outcome. The last century or so was an anomaly from most of human history; a trend created by the "arms race" of needing educated workers. The prisoner's dilemma was if you trained your workers in more efficient tech you could out-compete and take all the profits from competitors which gave those educated workers the means to strike (i.e. leverage). Now it is the "arms race" of educated AI, rather than workers which could invalidate a lot of assumptions our current society takes for granted in its structure.
