Without being self-destructive is the way to do it.
The longer a self-destructive mode of production has control over the means of production - the closer to annihilation the productive forces are.
Do an estimate and calculate the maximum lifespan and this is how much time is left before its too late.
My estimate is ≈120 years on its natural course (without experiencing changes), what's yours?
Development of the productive forces is already done. The context of those statements was to develop the proletariat out of the shadows of serfdom, which has already been the case globally for many, many years. Marx did not write down that we have to wait for AI intelligent robots before a socialist revolution can occur. Why there hasn't been a successful socialist revolution yet is another topic.
Now, people defending capital try to deny their intention by calling shit neo-colonialism (it's just imperialism stripped of Marxist theory), to justify support of bourgeois-on-bourgeois conflicts, where the proletariat take all the casualties. Their focus on "uplifting" the poor and exploited with economic (liberal) development (dengoids and Africa) is not only impossible, due to the need for the haute bourgeois to protect international profits with cheap labor, but also in defense of utopian, liberal idealism by affirming the theory that if liberalism is hard enough, world happiness will be achieved (but then there's a socialist revolution for no reason, woohoo).
>>2439283>Development of the productive forces is already done.wrong. The required productive forces for defense of the revolution is always relative to the external forces that seek to overthrow it. If AES states have to defend themselves from counter revolutionaries, then they are stuck in an arms race with counter revolutionaries. Just because they have enough productive forces to sustain themselves doesn't matter when they live in a world still dominated by capitalism.
Socialists states are in a holding pattern while they wait for you to overthrow your own bourgeoisie.
