This is the story of a man who jumped from one job to another, from one country to another, from DRC to Luxembourg, doing more or less the same thing, but in 2 different environments.
Indeed, the GDP in DRC is $312 per capita while it reaches $81,000 per capita in Luxembourg (around 260 times more).
It could have been worse, as actually Luxembourg is only the second richest country on earth, Qatar with $87,000 per capita per year is the richest. Full list is here: http://www.forbes.com/sites/bethgreenfield/2012/02/22/the-worlds-richest-countries/
