IIRC, the public sector defined pension plans (not CPP) are required by law/their own policies to set aside some huge sum of $$ to ensure the paying off of the retirees, and the investment of that sum is quite conservative, meaning that it won't suffer any huge losses. In fact, even at the height of the financial crisis, I don't think the this fund lost any money at all -- it's just that the gain was something minuscule like 1 to 4%.
Additionally, not all pension plans have inflation adjustments -- some do, but some only have partial ones, and some have none. . And then you have the current generation of contributors to pay into the plan, as well as the ability for the pension company to increase contribution amounts when the need arises, so the feasibility is not that bad ge.
