Richard Connell makes a very globalized statement when he gives Rainsford, in the short story "The Most Dangerous Game," the following line:
"The world is made up of two classes--the hunters and the huntees."
When examining the world today, as it was when the story was written (1924) and since the beginning of time, people have always been placed into the two categories: the hunted and the huntees.
When examining history, wars, disputes, hatreds, and even means of survival have been based upon ones ability to "hunt." Cannibals have hunted, killed and eaten people. Warring nations have hunted each other with the hope of destroying each other. People today constantly belittle those weaker than them simply to feel or look stronger.
It does not take killing someone for it to be considered hunting. Serial killers hunt their victims, stalking them to find just the right moment to pounce.
Therefore, yes, the world is (and always will be) full of those who hunt and those who are hunted.
