Let me say, firstly, that you seem to be posing your questions “at” me, rather than to me. (After all, this is a thread about netdrama, and you continually pose shortish challenges to me rather than, say, inviting me to participate in a thread designated for such discussions). So I will give a brief answer, but I would ask you to ratchet down the aggressiveness/arrogance, assuming I am reading your tone right (it is always hard to tell over the internet).
Pouncing on leftists when they rear their ugly heads in your backyard does not, of course, do anything to change anyone’s social outlook. You won’t actually have achieved anything for your ideas by having played whack-a-mole with leftists brave enough to show up on your turf, who at best will sulk away with their egos damaged, but their opinions intact. You won’t have learned a thing about what makes them tick. So now let us continue.
I consider myself, broadly, a Marxist (I’m not a Trotskyist, despite my sig). Marxism is, above all else, a way of viewing history. It is not a set of prescriptions for ‘the future society’; in fact, Marx is notorious (even with me-especially with me) for giving few details about how a socialist society would look. He overwhelmingly concerned himself with one thing: the historical movement of the working class whereby it comes to claim more of the value that it creates.
It is true that I have no respect for private property as such. If it serves a social function, fine, it can be preserved/tolerated. When it doesn’t serve such a function, then there is no reason for the state to give it legal recognition and physical protection.
If you disagree with this, then it is somewhat unlikely we will be able to have a truly productive discussion on the social benefits or functions of private property in present society. I will be looking for ways to make private interests give way to public ones, but admitting here and there that sometimes the two types of interests may coincide (in the short term at least). You, already convinced on a normative/“natural rights” basis that private property and private interests should not ever be impinged upon (except of course by other private interests), will be motivated to show that such interests always serve the public interest.
And indeed you seem to be already implicitly doing so in the question you pose above. One of the benefits of private property, you presumably believe, is that it coordinates production and distribution in a decentralized and “efficient” way. This is a social benefit of private property. But, what happened to natural rights?
I will give a very broad type of answer to how I think production might be planned “under socialism”: it would be coordinated using, at the minimum, all of the same methods that General Motors has at its disposal to plan production internally. Corporations don’t have an internal market; they don’t have internal prices. Corporations are giant islands of planning in a sea of markets, of cooperation in a sea of competition. Also, central “planning” is of course not the only option available to a democratic society for directing the productivity of whatever wealth it controls. I’m sure you are familiar with Lange’s ideas, and it’s unclear that “planning” which follows market inputs as he proposes is really engaging in “planning” at all.
Finally, I think we should take this to another thread. If you have a suggestion of one, give me the link, and I’ll read everything that’s been written in it so far.
