It appears Amon can energybend, or is somehow capable of some high level chi blocking maneuver. The Equalists have little intention of accepting the benders’ ability, or attempting to improve themselves, instead they wish to eliminate bending altogether. The justification they think they have is that bending has been the cause of war, inequality, and general human suffering. They are wrong, but that doesn’t change the fact they blame all their social ills on bender “oppression.” It’s as silly as modern leftists who blame all our social ills on capitalism.
When it comes to real life, the fact is that the naturally gifted are inclined to succeed. Whether they are endowed with a naturally higher intelligence and superior personality, or they are lucky enough to be born into an environment that encourages success, the truth remains they are the most capable. A meritocratic society necessitates these individuals take more complex duties upon themselves, and they do. Our capitalist system allows us to encourage these skilled individuals with greater profit, we want them to be rich and succeed because they are superior at their given job.
The same is true of the Avatar universe. Benders are far more capable of many jobs. Whether it’s military and police, industrial, or leadership. The benefits of having a bending military and police force are obvious, and we have seen on the recent episode that industrial business owners want benders as well (Mako at the energy plant). The leadership one is a bit more questionable, but we can infer the discipline and historical/spiritual training professional benders get makes them better at the job. Let’s also remember the wealthy families will be able to provide a better education to their children, bending children born to wealthy families will grow up a better potential leader.
The problem is simple, does equality make up for the poorer, more violent society that results from it? It’s silly to think they wouldn’t have war, or general “oppression,” without benders, we have even seen in the Avatar show that non-benders can be ruthless and manipulative. We have even seen non-benders fight equally with benders, even Jet’s untrained group of teenagers could take on benders (not to mention chi blockers). And let’s not forget balance, or “equality” if you wish, is the reason they have had the Avatar!
