According to Osho, communism is a radical, need-based, classless vision that abolishes private property and competition, serving as a foundation for spiritual growth; socialism is a compromise that keeps capitalist incentives—property, merit pay ('each according to his work')—which revives classes and ambition. Thus socialism moves backward toward capitalism, while authentic communism demands inner consciousness change and a revolutionary restructuring of society.
Communism shares by need and ends competition; socialism still keeps some capitalist rewards like property and pay-by-work, so inequality returns.
