 However, by 2010, around 25% of Canadian workers were still unionized while 11% of American workers were unionized.Krugman blames Reagan for this rapid decline in unionization because he "declared open season on unions" while the global market clearly made room for unions as Canada's high union rate proves.Contrary to the arguments made by Chicago economists such as Gary Becker, Krugman points out that while the wealth gap between the college educated and non-college educated continues to grow, the largest rise in income inequality is between the well-educated-college graduates and college graduates, and not between college graduates and non-college graduates.
