Inferiority complexes run rampant in organizations. Truth? It isn’t the organizations that create the issue but rather the structures that reinforce it.
Consider the fact that school systems teach rules. Rule number one: Put authority figures (teachers, parents, guardians, etc.) up on pedestals. Respect these individuals who have authority (aka power) over you, and take what they say as gospel truth. Even if what they say is negative and nonsupportive, believe it anyway.
This mentality gets reinforced in organizational structures where individuals find themselves in parallel circumstances, dealing with hierarchies and rank. The automatic (often subconscious) response is to go back to that originally programmed behavior, which often results in feeling inferior and less important than others.
