The part of this section that stood out for me begins with section 17, “Will it be possible for private property to be abolished at one stroke?”, where Engels basically explains that there is no instant communism button:

No, no more than existing forces of production can at one stroke be multiplied to the extent necessary for the creation of a communal society.

In all probability, the proletarian revolution will transform existing society gradually and will be able to abolish private property only when the means of production are available in sufficient quantity.

Very often, people ask, “What will XYZ be like under communism/‘after the revolution’?” asking about various laws, industries, work, housing, and ways of manufacturing and acquiring goods and services. I think in many cases, the answer to these questions is a lot more mundane than some people might initially imagine. We see in section 18 a series of ideas of what a proletarian-led society might democratically implement for itself at the start of proletarian leadership. And, as OP pointed out, we see many of these (or similar) measures underway in AES countries today, providing us real-life examples of the process that we can learn from as it develops.

I think it’s worth noting that Engels points out that these would basically be democratic measures undertaken by the proletarian-led society to continually reduce the prevalence of private property, using various methods to increasingly concentrate “all capital, all agriculture, all transport, all trade” into the hands of the proletarian state, with the basic aim of ensuring the livelihood of the proletariat, and multiplying the society’s productive forces until “production will so expand and man so change that society will be able to slough off whatever of its old economic habits may remain.”

As we can see from the real-life AES examples, this is a long process, with some changes being rapid and dramatic and easily intuitive to the average person, and others taking decades of time and having many possible approaches as well as many possible pitfalls, since longer term and larger scale generational changes like that are often harder for people to perceive and carry out from their individual position without learning more in depth about it. (Actually, on that point, I am glad that Engels specifically mentions education in section 18, as I believe it’s an important part in conveying the function of these longer generational processes to individuals in the society and strengthening their self-understanding of how they participate in building and directing their society.)

I think sections 17-20 could be good to go over with people who seem unclear on how (or why) socialist construction would take place, and on the meaning of terms like socialist-oriented market economy, socialist market economy, etc., as well as going into the reasons why development of the means of production is important (and how and why imperialism purposely hinders and sabotages that development in certain places).

Those are my thoughts, if anyone notices errors in my reasoning or understanding of the text, please point them out.

Thanks for leading this study group, I’m looking forward to its continuation.
