I want to be a Billionare?

When I look at overly rich neighborhoods it overwhelms me. I understand that some people actually earned their way up, but there is no reason why a person should live in a mansion when they only occupy 1/3rd of the square footage under their feet. Does anyone ever think about regulating themselves? To know when to say STOP. If you have enough to the point that you do not know what to spend it on, think about the scarcity of the world. The distribution of wealth is BEYOND unfair. There are NO words to describe it. When I see mansions, shiny cars and beautiful people I do not feel aspired nor mesmerized. I feel disheartened by the inequality.
