The only way to fix the world, and it's manufactured social and political problems, is to evaporate organized leadership off the face of the Earth.
Our world and military leaders, politicians, and even the intellecual elite (including the media), all have a hand in helping segment individuals into groups based on (mostly arbitrary) external factors. These include race, ethnicity, sexual identity, political affiliation, class, and so many more. When we look at how many involuntaty groups and subgroups we are "apart of" it's easy to see why it's so hard to find peace. Not that we will ever find peace (or that it should be our goal), but there are just some things that the individual has no real hand in. Genocide, warfare, mass pollution, the disenfranchising of people, the list goes on. It simply isn't our fault. People don't start wars, organize death camps, or create social policies that destroy or oppress large portions of populations. They don't enslave, and certainly by themselves cannot bring about the destruction of mankind.
We fight each other because we're told to. We hate each other because we're told to. We kill each other because we're told to.
Let's stop thinking about "us," "we," and "them." How about "I?" We need to start thinking and acting for ourselves. We need to realize that the free self is the only important unit of society that we need to be concerned with. We need to recognize the importance of voluntary interaction amongst people in an open world. We need to teach our children that selfishness and free will are just as imporant as charity and selflessness. (Also the proper definition of selfishness and free will, that would help a lot. Maybe it would put an end to all this high school type Objectivist thinking.)
I think most people feel the same way you do about our current situation. We all just have a different way of looking at it. We're living in a crazy world, probably always will. But is it really our fault? We need to stop looking up to our leaders, and even to each other for help.
I'm ranting, but hopefully it makes some sense, and is at least relevant to your post
