@SarahGen-- That's a good point. I think you're right that many countries rely on one or two factors of growth predominantly. Middle Eastern countries rely too much on natural resources, other countries rely too much on investment. Policy makers are not thinking long term. They are looking for a quick fix but a quick fix doesn't really exist. The economy may do fine for a while, but once that factor has been used up or if there is some other issue, the economy will plummet quickly.
