I haven’t yet read Marx’s manifesto, so I’m not qualified to weigh in on it’s ideas. But I strongly believe ”workers should own their means of production”. The rhetoric itself tired and misunderstood (which we should be blaming upper-middle class academic elitists for). What is “production”?
the dominant cliche is a late 1800s factory with workers holding up their hammers and sickles. But a factory is not a pleasant place for many people to work, and capitalism itself synonymous with factories. Mass production, tedious labor, and quantity over quality. This is not the same “production” seen by works of centuries old artisans and crafters in British museums
for thousands of years, technological progress was stable, not exponential. The competitive edge to being a “early adopter” was not really a thing. So, the “means of production” for most of human history meant living off the land and being self reliant in a hostile world
To me, “owning the means of production” is about meeting your own needs. If a person can choose how they want to work, live off the land where they work, trade what they produce with their neighbors, and build a social safety net in the form of people who genuinely care for them, they have already produced something that goes beyond them. But they did so in the process of meeting the lower half of their hierarchy of needs in the process. And that is intangible value. It might not produce material goods that require scaled supply chains like medicines, computers, and automobiles, the degree to which more of those things improves our quality of life is questionable anyways
