Letter to the National Post (November 23, 2012) This article on the Fraser Institute’s take on income mobility confuses personal income growth with (inter-generational) income mobility. Over a course of a lifetime income rises as people get promoted, etc., and typically peaks in the 40s and 50s. So there’s no surprise that 83% of the lowest earners move up the income ladder over a decade. Income mobility, as it is commonly understood or measured by economists, looks at how well parental income predicts offspring income. What is important to know is where in the income distribution were Charles Lammam’s parents at similar age-experience profile. Studies on inter-generational income mobility (a.k.a. “economic mobility”) show greater portability of Canadian society vis-à-vis the United States; however, this does not negate the fact that income inequality, especially at the very top end, has been on a steep rise in Canada.
