Thanks for bringing GAPMINDER.com to my attention.  

There is no question that the gap between countries has narrowed but income equality within developed and developing economies continues to rise and therein lies the problem.   

The Conference Board of Canada has this to say about our situation: "Canada gets a “C” grade and -ranks 12th out of 17 peer countries.
-Income inequality in Canada has increased over the past 20 years.
-Since 1990, the richest group of Canadians has increased its share of total national income, while the poorest and middle-income groups has lost share."

It is true that service and other jobs have been created however insufficient attention has been paid to develop domestic markets and raise living standards.  If a country uses cheap labor to  concentrate on export markets the monies so earned naturally go to those who control the means of production.
