Why do you believe it is stronger? The fact that Capitalism’s decentralized markets result in centralized monopolist syndicates is exactly why Marx predicted Socialism to be the next stage in Mode of Production. Marx said it best in the Manifesto of the Communist Party:

The essential condition for the existence, and for the sway of the bourgeois class, is the formation and augmentation of capital; the condition for capital is wage-labour. Wage-labour rests exclusively on competition between the labourers. The advance of industry, whose involuntary promoter is the bourgeoisie, replaces the isolation of the labourers, due to competition, by their revolutionary combination, due to association. The development of Modern Industry, therefore, cuts from under its feet the very foundation on which the bourgeoisie produces and appropriates products. What the bourgeoisie, therefore, produces, above all, are its own grave-diggers. Its fall and the victory of the proletariat are equally inevitable.

Lenin further analyzed these monopolist syndicates and described why we are seeing dying, decaying Capitalism in his work Imperialism, the Highest Stage of Capitalism. Once competition begins to die out, the Rate of Profit sinks and these Monopolist Syndicates strangle each other. The only way to fight this rate of falling, other than further automation which further lowers the rate of profit, is joining each other in ever larger syndicates, which is not infinitely replicatable. Capitalism is in its death throes.
