He predicted that: While capitalists get richer, workers’ wages will, with a few short-lived exceptions, remain at or near the subsistence level. More and more independent producers will be forced down into the proletariat, leaving a few rich capitalists and a growing mass of poor workers. The rate of profit will fall. Capitalism will collapse or be overthrown because of its internal contradictions. Proletarian revolutions will occur in the most industrially advanced countries.
