I have asked this question from day 1----Germany/Italy/England/France were decimated and largely in ruins after the end of WWII and yet were able  to develop vibrant/successful economies in the years since--meanwhile Somalia,  Sudan, Libya, Yemen etc remain sespools despite foreign aid and in many cases sitting on vast natural resources (i.e oil-Libya)--why can't the people of these countries not take the example of the countries of  Europe and improve their own countries??
