Socialism can not be realized on the basis of injustice, overcoming alienation - the main problem of socialism. The problem of alienation is directly connected with social justice and is a vital life for socialism, not only because historical experience has demonstrated a variety of deforming the essence of socialism forms of alienation. Despite the fact that the whole story is the overcoming of alienation, some forms of exclusion contribute to human development in historically limited conditions of pre-socialist formations. It is obvious that socialism was buried in his own limitations as a crude and imperfect communism. Unlike capitalism, which develops on the basis of alienation, socialism can exist and develop only if overcome and destroyed injustice and historical forms of alienation.
