 Bernstein also attempted to demonstrate empirically that huge firms were not as profitable as small-scale ones, arguing that all sizes of companies could survive well together.Bernstein challenged orthodox Marxist theories that capitalism was doomed to fail, noting that capitalism was increasingly overcoming a number of its frailties “such as unemployment, overproduction, and the inequitable distribution of wealth.” Moreover, Bernstein claimed that the apparent stabilization of capitalism was not temporary but a permanent feature.Bernstein contended that the income of the proletariat was rising, which directly contradicted Marx's conjecture that workers would become poorer due to capitalism's insoluble contradictions, oppression of workers and oppressed class mold, and profit-based structure.
