Can we save Ghana?

Really it's not an easy question. What can I say, probably no.
Now I'm spending one month in a social volunteering project in Ghana, and I'm in a village il Northern region. Village's name is Langbensi. I'm working in a clinic, and what I do is to weight and vaccine children and assist pregnant woman. I also talk every day to people in the clinic about HIV, malaria and sanitation. But all I do is nothing. This people don't need me, don't need my help, they need a radical change. It's necessary and very urgent a school reform, and a police reform too. Here police is completely absent, in Accra (the capital) i found 3 drugs dealers in one hour. And they tried to sell me a gun too. It's crazy. Population in villages need to change their way of think, they don't care about HIV or malaria or tbc even if we volunteers tell them that's very dangerous. They don't need money, they need to fight ignorance and need democracy. So what can we do?
