No disrespect. I only use official data from those official international organizations, such as the OECD, for example. The OECD has studied this in Pensions at a Glance, which they publish every two years, and it is non-partisan. It is funded by Canada and all the other OECD countries.
They have said very simply that public pensions are unsustainable in the western world, and there are very serious people who have said that, including Governor Carney. I've looked at it.
We're living a lot longer. I want to put this on very quickly, because people quote the life expectancy figure based on mortality over an entire lifetime. When you achieve the age of 65—so all the people who died before you are not part of your statistic any longer—you have a life expectancy of 84, for a female, and 82 for a male. So we cannot, as Greece is demonstrating brilliantly, and Spain and France, continue with policies where we are living 15 and 20 years longer than only 30 or 40 years ago.
The second point, to address your question, is that we are facing looming labour shortages. It is irresponsible to pay people to be unemployed in one part of the country when there are desperate shortages in another part, or just push them out the door into retirement when we need them in the economy to be able to fund people like me, when I retire.
