We are all familiar with the quote "life is not fair ". Actually, life is fair, people are not.
Some people think that they are more powerful or ahead of others because they have more money or riches. Some are more beautiful., some are more highly educated. The tendency of this they humiliate others who are below of them.
They treat better those people who are highly profiled. Those who have everything, those who are beautiful. The low profile people are humiliated, they treat as trash or something not important.
We are all equal it's just that some people think they own everything or own the world. We are all boarders in this world we don't own anything, even our lives. The one who can only claim or who own everything in this world is God.
