Yes, this is the essence of Marx’s scientific critique of capitalism:
Capital itself is the moving contradiction, [in] that it presses to reduce labour time to a minimum, while it posits labour time, on the other side, as the sole measure and source of wealth.
Leftist agitation can’t resolve the contradiction. The inexorable working out of capital can transcend it.
Marx is saying that capital compels its puppets, the capital-accumulating class, to progressively devalue (in capitalist economic terms) the social means of production.
Capital is inexorably ushering in the demise of its own mode of production — its own possibility of existence. That is Marxian materialist dialectics!
Despite of, and in the teeth of, the liberal ‘philosophical’ doubters and academic ‘politico-economic’ deniers, Marx is here saying nothing more than the implications of his general scientific materialism and of his specific labour-time theory of capitalist value.
To comprehend why Marx can say this is a sure-fire way of comprehending the necessity and inevitability of socialism.
