If you want to compare GDP per capita between countries, you must use the purchasing power parity GDP.

Beliefs form through what we see, hear, perceive, think and feel throughout our lives. In my particular case, some of my beliefs originate in my childhood. These beliefs were inherited from my parents and they inherited from their parents. With that I can say that my first beliefs had origins in my family, with the teachings of what my parents had as true and right.
Over time,  my thoughts and personality have been influenced and impacted by the “outside world,” the world outside my family zone. These impacts and influences eventually transformed some concepts and modified some beliefs that originated in the family environment. With this I can say that some of my beliefs originate in my experiences and what I have heard, seen and absorbed from the world.
