Socialist thinkers prior to Marx and Engels, such as Fourier, Owen, and Bebel, had been able to do no more than moralize about existing social inequalities, positing an ideal world where class privilege and exploitation should not exist – in the same way that early feminist thinkers posited a world where male privilege and exploitation ought not exist – by mere virtue of good will. In both cases, because the early thinkers did not really understand how the social injustice had evolved, maintained itself, or could be eliminated, their ideas existed in a cultural vacuum, utopian.
