May I remember that Marx saw a limit (Schranke) to capitalism, due to the development of productivity (B.3, ch 15)?
In fact, there are two Marxs: 1. The one of the "absolute surplus value" as the main factor of accumulation. That "surplus value" being extracted from the work of each producer, the accumulation is then endogenous. Such an accumulation has no limit, and capitalism can exist forever. So that the solution is either to make socialism inside capitalism, it is the social-democrat way, or to make a revolution, it is the Leninist way. 2. The Marx of the "relative surplus value" and of trending profit rate to fall, for whom productivity is the main factor of accumulation (B.3, ch.15, paragraph 3). Rosa Luxemburg pointed out that this conception could not support an endogenous accumulation and requested an expansionism, what was attested by colonialism (Die Akkumulation des Kapitales, 1913). Such a process is likely to periodically meet a limit, up to the last one: the planetary one. The related capitalism is condemned to die, even though no revolution succeeds in subverting it. Additionally, Leninist conception saw a world forever divided by the conflicts of interests between the various imperialist states, continuing at the planetary level the class struggle of within each of them. For her part, Rosa Luxemburg saw an indistinct imperialism relentlessly continuing the colonizing process. Between this two conceptions, history has decided. The dictatorship of proletariat is a failure and a persistent after-tragedy, and the USA have put an end to the conflicts between imperialist states, by a leadership with which all of them have agreed totally (except general de Gaulle's interlude) and have even demanded. Finally, under IMF's management, the "globalization" is restoring the colonialist subjection and extending it, as a trend, to all countries. So that the hypothesis of the limit, and moreover of the last one, is today much more accurate than the Leninist theory. The question is: does it remain space enough for a new remission before the end? Russia? China? RK
