How can you make rent profitable, if you can't add anything rentier can't add himself (since labour has no input in production)?
They have no choice but to do it, as there is no central authority over them to make them keep their agreements binding.
It's called "dialectical materialism". But 'murricans aren't taught philosophy, so you literally can't understand the problem. Transition from Capitalism to Communism for you like flicking the switch. Even when pointed out that such a period lasts longer than a blink of an eye, you can only think that switch is being flipped real slow.
And all of this is still Capitalism? Capitalism that still exists from point zero, until … what point exactly?
> Corresponding to this is also a political transition period in which the state can be nothing but the revolutionary dictatorship of the proletariat.
And what about economy, señor Expert? What modes of production are used in economy? Transitionary?
Communism is a classless society, only if communism is understood as a vernacular for society that tends to emerge under communist mode of production (i.e. social production for use).
Once we separate those, once we recognize the difference between Basis and Superstructure, once we stop conflating modes of production and societies that are shaped by them, the picture becomes completely different and any notions of lower stage communism somehow not existing under DotP - or abolition of DotP being prerequisite for Communism - turn utterly ludicrous.
Just like Feudal state was not abolished overnight - despite Capitalist mode of production growing alongside it and becoming dominant for many decades (if not centuries) - so would DotP co-exist alongside growing Communist mode of production for a long time.
Except it is not society that defines classes, but classes (which are inherent to modes of production) define society.
Consequently, it is not society that you should be looking at, but modes of production. I.e. only as far as Communist mode of production extends and manifests itself, can classless society extend and manifest itself.
