The term "lunatics" used in your question is quite strong and pejorative, so let's approach this topic with a more objective and neutral language.
It is essential to recognize that individuals who display a sense of entitlement to anything or anyone they want have complex psychological and behavioral factors contributing to their mindset. While upbringing and environment can play a significant role in shaping a person's beliefs and behaviors, there are additional factors to consider:
Narcissistic Personality Traits: Some individuals with narcissistic personality traits believe they are entitled to special treatment and are above the rules that apply to others. They have an inflated sense of self-importance and lack empathy for others.
Power and Control: People who seek power and control over others may develop an entitlement mindset as a way to assert dominance and satisfy their desires without regard for others' rights or consent.
Social Reinforcement: In certain social circles or cultures, entitlement may be reinforced or even rewarded, leading individuals to believe their behavior is acceptable or justified.
Cognitive Biases: Cognitive biases, such as the illusion of superiority or the fundamental attribution error (attributing others' behavior to character flaws while excusing one's own behavior as situational), can contribute to an entitlement mentality.
Lack of Empathy: Individuals with a limited ability to empathize with others may have difficulty understanding or caring about the impact of their actions on others, leading to a sense of entitlement.
Psychological Disorders: Some mental health conditions, such as certain personality disorders or antisocial behavior patterns, can contribute to an entitlement mindset.
Reinforcement of Past Behavior: If someone has repeatedly received what they wanted without consequences, they might develop an entitled attitude as they believe their actions always yield the desired outcomes.
It is crucial to remember that this behavior is not indicative of the majority of people, and it is not fair to label all individuals based on the actions of a few. Understanding the underlying reasons behind such behaviors is important for creating interventions, support, and solutions for addressing entitlement and its potential negative consequences. Professional help, such as therapy and counseling, can be beneficial for individuals who display entitlement issues, helping them develop healthier attitudes and behaviors.
