Resource curse

Resource curse thesis The idea that resources might be more of an economic curse than a blessing began to emerge in debates in the 1950s and 1960s about the economic problems of low and middle-income countries However in 1711 The Spectator wrote It is generally observed that in countries of the greatest plenty there is the poorest living so this was not a completely new observation

The Effects and Economic Impact of Corrosion CORROSION is a natural process Just like water flows to the lowest level all natural processes tend toward the lowest possible energy states Thus for example iron and steel have a natural tendency to com-bine with other chemical elements to return to their lowest energy states
