Need and Want

There is a struggle that comes with living overseas. It's carried over from the culture I was born into as well as a struggle that reigns within the country I live in. It's a struggle between two worlds, two realities. Rich vs. poor. Abundance vs. lack. How do I live with the guilt of what I have been blessed with while so many have so little?
American culture says we need a lot. We need everything. We need everything newer. We need everything bigger and flashier. We need everything that is better. Without leaving the borders of the U.S., I probably never would have noticed this. When I speak about this to those that have never stepped into a third world country, I am usually met with a blank stare.
But, the problem is obvious. And it's not just America vs. Uganda. Even within Uganda, it's obvious between the haves and the have nots. It's the same struggle.
Most of the time I'm content with what I have. I might occassionaly crave a food from home or long for a new shirt, jeans, or pair of shoes. But, mostly, I am content. However, once in a while, I struggle with those cultural pressures, the desires (lies) that lead me to believe that my wants are really needs. There's the struggle: how can I feel that way when I look at the environment around me?
I don't really need most of what I own but find myself wanting more. The life I live in Uganda is not a hard life, especially when compared to others. I spent my first several years here living in a one room shack, no electricity, no water. I traded that in for a two bedroom apartment. And am again trading my two bedroom apartment in for a three bedroom house.
It's still stretching at times. Water and power go off, sometimes for weeks at a time. But, I'm not living in a house that leaks. Me and my small family are not crowded into a tiny space. I can afford medicine when we need it. We don't sleep hungry (although I wish we could afford more meat- again, a want not a need). Yes, it gets hot at times. But, we can open up the windows for fresh air and not worry about the smell of sewage creeping in.
So, in writing this, I have found no answers. The struggle will continue. All I can do is pray that I find a healthy balance while living in an unjust world.
