We are all intellectual capitalists

Many problems that arise out of conflict in society between people, organizations, nations, and so on, are a direct result of how our biological brain's design.

We are all intellectual capitalists.

What is capitalist? 

A capitalism is a system of interaction between individuals about objects. Normally, it is the system of trading physical objects or abstract services between those that participate.

It is not accidental why we evolved to this kind of society system.

Our brains' operation is capitalistic. Our brain considers ideas of value, or not, and takes in the valuable and throws out the non-valuable.  It doesn't matter what the topic is, how it is met in the open in society, and makes personal decisions based on beliefs and reason one each.

We seek things that answer our Maslow's hierarchy of needs. We repel things that, we believe, take us away from those same needs.

In the process, we determine that ideas, like people and other objects, are part of how we get there on this journey. At the same time, we also reject ideas, like people and other objects that will not help us get there.

We treat ideas like real objects because to an evolved brain there is little distinction between the imaginary and the real. It's not a bug, it's a feature.
