It appears that the developed countries have mid to high levels of alcohol consumption; from this we can conclude that if you want the following:

-high income per capita
-high human development index (HDI)
-high gross domestic product (GDP) per capita
-more energy consumption
-produce and trade more consumer goods
-higher literacy rate
-longer life expectancy
-lower infant mortality rate
-wide and varied infrastructure
-organized government
-manufacturing and technological inovation
-a free press and aa informed public
-universal, and in most cases, free healthcare
-gives overseas aid

then you need to drink more! :P
