Ideas of Man in Management

Whenever I sit in management seminars or read management literature, I throw this question back at the content. With unfortunately quite unsatisfactory results at the moment: the idea of man behind current management ideology seems to be quite consistently – despite different topics and approaches – one that conceives man as exclusively good (and good-natured). One would still face obstacles to live up to this – lack of acceptance of emotions or poor reflection on humanity or bad organization – but if these obstacles were overcome, then the good and right would always win (and companies would then, of course, be even more successful).
It is a thoroughly naïve view of humanity that, confronted with Büchner's question of what it is in us that goes whoring, lies, steals and murders, can only turn away and cover its ears. This is interesting because the image of the classic manager is that of a rational decision-maker who cannot avoid a realistic image of man as a precondition for his rationality. The current management literature stands in fundamental opposition to this.
