Power of privilege

There are always privilege people in every society. Either because of race, culture, religion, economic statues and many others. 
There is always someone who has the power in every city, state, and country. Is there any way to change it? I do not think so. Many countries have tried different systems to govern and find equality like socialism or communism.
 For many years there has been major discrimination in the world. A country like United States has divisions because of skin color, since the day the became a nation. A country like Colombia is more known for economic statues discriminations, people with low incomes have the lower benefits and get almost any power. But will this segregation ever stop?  

“What is it you most dislike? Stupidity, especially in its nastiest forms of racism and superstition.”
