"By the way, you did know that anarchism and Marxism are mutually opposed and incompatible political movements?"
The fact the you start the sentence with "By the way" indicates that you know it's off-topic. It's also an invitation to a fucking boring-ass played-out thread that, if even worth engaging with, isn't suited to Practice and Propaganda.
I appreciate that the rest of your post is on-topic, which is why it stayed whereas all of the responses to it got trashed. Give me some credit here - I'm not picking on you. That said you're almost at the 1000 post mark - you should know better, and put some baseline minimum effort into maintaining a useful discussion.
That's cool that you like it. The idea of the "opportunity cost" can be googled pretty easily. Also it is in Wiki. I think it is pretty much mainstream economics now. What they say is that "opportunity cost" is a cost which is not subject to any accounting method in the traditional sense, i.e. that you really can't account for it with acutal numbers. They then say that opportunity cost is an "economic cost", but, again, that it cannot be defined mathematically for accounting purposes...I call it an "imaginary" cost. They then use the opportunity cost as the explanation for profit. The whole argument falls apart as soon as you look at it, but I am pretty sure it is being taught in economics. You might want to check with Paul Cockshott, he is up on the latest economic theory.
Hey, would you mind providing me with a source for the recently proposed "imaginary cost" mentioned here; http://www.revleft.com/vb/showpost.p...2&postcount=10
This appears to be next to a straight-up acknowledgement of the law of value from how you framed it and I am very interested in reading of it. Thanks!
