I see where you’re coming from, but is this really the main source of the inequality?
Based on numbers relating to workers’ diminishing share of profits, it seems to be that the capital class has been able to take a bigger piece of the profit pie without sharing. In the past, companies have shared profits more widely due to benevolence (it happens), government edict (e.g., ww2 era), or social/political pressure (e.g., post-war boom).
Fwiw, I think that the mid-20th century build up of the middle class was an anomaly (sadly), and perhaps we are just reverting to the norm in terms of capital class and worker class extremes.
I see tons of super skilled folks still getting financially fucked by the capital class simply because there is no real option other than to try to attempt to become part of the capital class.
