The question of the factors that have been contributing to inequality were discussed by Professor Boadway I think very well—i.e., that things like technological change, the move of manufacturing overseas, and the loss of manufacturing employment have contributed to that problem.
On the increase in salaries, it's true that salaries have not increased to the same extent that the GDP has over the years. There has been some increase recently. There was a substantial decrease in the early 1990s, in particular, in incomes across Canada. We spent most of the rest of the decade and into the 2000s catching up on average for the entire economy.
I think one of the things that happened at the same time was that there became, over that same time period, an increase in the premium of particular types of skilled labour. Through technological change and other factors, these skilled jobs became much more valuable to our economy, and so we saw a polarization over that period.
