But what's interesting is that it also has a relative point. If a person lives and works where the majority earns and spends a million dollars a year then someone that makes and spends $300k will feel poor since they can't buy the same amount of goods and services. Yet, most people would laugh at calling someone like that poor.
An interesting example is how the children of John D. Rockefeller were raised. They were raised without the trappings of wealth. The clothing of the younger kids were hand me downs, they got a small allowance and they had to do chores around the house. Yet they lived and went to school in the richest area in America and their father was the richest man in the world at the time. I bet those kids felt disadvantaged since their peers had the trappings of wealth. Yet we would all laugh at the thought.
Another interesting example is Gavin Newsom, California's current governor. When you hear him speak about his childhood you get the idea that he was raised in a very poor area in California. He actually grew up in one of the most affluent areas in San Fransisco. I bet his family was poor relative to his peers so, therefore, he feels he grew up disadvantaged.
