In the post-industrial world creativity becomes more and more important: Richard Florida points out the dawn of the "creative economy"; furthermore, Joseph Pine II and James Gilmore point out that every business should be as original as a drama, if it wants to avoid being involved in a price competition. Do all these mean that the idea of an avant-garde artist, "Everyone is an artist," has in twenty years finally been realized in the practical world such as in economy and management? In this interdisciplinary study I try to answer this question, which also contributes to reevaluation and actualization of Beuys' thought. The focus of the matter is his definition of creativity as a liberating force which encourages us to determine ourselves and codetermine the society. Based on this definition "creative economy" can't to be truly creative as long as profit making incentive on the managing side has more priority than the pursuit of quality and self-realization of the workers.
