America vs. Third World

I'm curious as to why in America so many people are diagnosed with various disorders such as ADHD or insomnia or depression or countless other mental disorders and yet these issues seem to be on the back burner when it comes to social awareness. In America there is a lot of support and medicine for people with these problems and it seems like most Americans are familiar with how these disorders affect people. But in the "third world" for example, it is widely ignored.

I think the obvious reason for this difference is that countries in the third world maybe have more problems that sweep the entire country (like genocide or debt or civil war etc.) and force the governments and society to focus on that matter. People in America are lucky enough not to have to worry about those things everyday. I can see how people who suffer from depression in Darfur, for instance, might not get individual attention. I can also see why the government of Sudan might not focus on finding a way to offer these people some help and security.

I guess what I'm trying to say is, does America make a bigger deal out of these disorders, because we can?
