Post-structuralism as the reason for mismanagement

This is my short consideration (as I had promised) of the basic concepts of post-structuralism.

Its general practices say:

"Post-structuralists hold that the concept of "self" as a singular and coherent entity is a fictional construct. Instead, an individual comprises conflicting tensions and knowledge claims (e.g. gender, class, profession, etc.). Therefore, to properly study a text a reader must understand how the work is related to his or her own personal concept of self. This self-perception plays a critical role in one's interpretation of meaning. While different thinkers' views on the self (or the subject) vary, it is often said to be constituted by discourse(s).

The author's intended meaning, such as it is (for the author's identity as a stable "self" with a single, discernible "intent" is also a fictional construct), is secondary to the meaning that the reader perceives".

"Self" refers to the individual viewpoint and practically means that the reader do not want understand what the author says. Execution of the written actions, negotiation and managerial corrections are impossible. That totalitarianism of «self» transforms opinions* into "facts**" and managerial practice into insisting that opinions are "facts".

* Opinion - belief not founded on certainty or proof but on what seems probable; a judgment given by an expert.
** Fact - an event or thing known to have happened or existed; a truth that can be proved from experience or observation.

"Post-structuralism rejects the idea of a literary text having a single purpose, a single meaning, or one singular existence. Instead, every individual reader creates a new and individual purpose, meaning, and existence for a given text. To step outside of literary theory, this position is generalizable to any situation where a subject perceives a sign".

It is the very case when the defect of the methodology is being carried to truth. Yes, the literary text usually has many meanings (that is why reader can not create them, but can making them known). It is seen, if to translate text in wordings of actions. But the problem of management is to choose the correct meaning and execute it. Otherwise the text viruses execute themselves in the form of opinions, which is known as freedom of self-expression (Text viruses. An introduction to "text viruses" - the human made infection that leads to mismanagement, p. 10).

If so, who said that the West leads in management and knowledge issues?
