Controlling 8 billion people is an incredibly complex task and not something that can be easily accomplished by just a few individuals. However, there are several mechanisms and systems that can influence and exert control over large populations. Here are a few factors that can play a role:

Government and political systems: Governments have the ability to create and enforce laws, regulations, and policies that can shape the behavior and actions of their citizens. Political leaders and institutions can exert control through legislation, surveillance, and the allocation of resources.

Media and propaganda: Mass media, including television, radio, and the internet, can be used to shape public opinion, disseminate information, and influence people's beliefs and behaviors. Propaganda and manipulation techniques can be employed to control narratives and manipulate public perception.

Economic systems: Those who control economic resources and industries can exert influence over individuals and societies. Corporations, banks, and financial institutions can impact employment, access to resources, and the overall economic well-being of people.

Social and cultural norms: Societal norms and cultural values play a significant role in shaping individual behavior. Those in power can influence and control these norms through education, social institutions, and cultural production, thereby shaping how people think and act.

Technology and surveillance: Advancements in technology have increased the potential for surveillance and data collection, allowing those in power to monitor and track individuals' activities. This can be used as a tool for control and manipulation.

Fear and coercion: The use of fear, intimidation, and coercion can be employed to control and manipulate populations. This can range from physical force and violence to psychological tactics aimed at instilling fear and compliance.

It is important to note that while these factors can be influential, they do not guarantee complete control over individuals. People have agency and can resist control through various means, including activism, organizing, and challenging oppressive systems. Societies are complex, and power dynamics are multifaceted, so control is often a complex and ongoing process.
