When you take a deep look at the richest countries and the wealthiest people in the world, you suddenly notice a profound pattern.
The richest countries are those which committed the most genocides, crimes and violence, and the wealthiest people are in majority the descendants of the people who benefited from those crimes.
The world caste system is a pyramid with the criminals or descendants of criminals on the top. Those people know that crime pays, and crime is more lucrative than any other human endeavors.
Violence in the world would not stop as far as we reward crime more than peace and justice.
