There are three separate and related developments behind the increasing inequality of earnings and incomes in Canada, each being the outcome of a particular set of inter-related factors. If public policy is being crafted to address inequality it needs to be aware of each of these, and of their underlying determinants.
Inequality has increased because those in the lower part of the wage distribution—often with less education and other skills— have not experienced significant if any increases in their earnings.
Inequality has increased because those in the upper end of the wage distribution—often those with above average levels of education and more job experience—have seen increases in their earnings.
And finally, inequality has increased, to some very important degree, because those at the very upper end of the wage distribution—the top 1% and even the top 1/10th of one percent—have experienced significant increases in their earnings.
