Poor and Stuck in One Place

 
Congo is a vast country.  It is the third largest country in Africa.  Congo, compared to the continental US, is about a third of its size.

Now, imagine you have to walk to most places.  There are no trans-country railroads or highways.  All trans-country transportation is done by plane.

Therefore, air transportation is limited to the rich.  The lack of common and public transportation truly effects the poor.  Travel opportunities are non-existent.
