From Thomas Sowell's book "Applied Economics", "All the numerous interacting factors behind economic development make it virtually impossible that different parts of the world would all have equal development, and therefore equal standards of living, at any given time. Yet the puzzlement, unease and dissatisfaction caused by seeing large economic disparities between societies have created demands for explanations - usually without creating an equal demand for years of study of the historical, geographical and economic factors behind these disparities. Instead, there has been a demand for simple and emotionally satisfying explanations, especially melodramatic explanations with ideological overtones...to solutions favored by those inclined toward controlling other people's lives."
