It appears to be a frequent occurrence for proclamations based on strongly held beliefs to be made that something is impossible, until it isn't. The balance of labor and capital is inevitably in tension perpetually, and I am simply arguing for more balance. Success is not assured, by any means, but that is no reason to accept the status quo in silence. There is always nuance, and I think it's unhelpful in the discussion to say "it won't work because of x." But that's not a conversation. The conversation is, "here are challenges with the current economic configuration, and here are some levers that could be pulled to make changes where there is a more equitable outcome for those who are getting the short end of the stick."

There is a wide gap between capital sucking up all of the productivity with workers being slave labor and Marxists seizing the means of production and burning it all down; neither is being argued for, but somewhere solidly in the middle of those extremes. Capital makes some sort of return, value is created, workers are treated fairly, receive reasonable compensation for the value they're creating, and have a seat at the table of the org, and everyone goes home happy. If someone is more of an Ayn Rand/Libertarian/individual exceptionalism sort of a person, this view is likely unpalatable, and there is no common ground to meet at.
