First of all, I think right now if spending was held down for the next number of years, to grow with population and prices as an example, and we were able to deal with some of our other issues that we need to deal with, I think we're okay.
However, if we keep running large deficits over the next number of years and debt continues to pile up where net debt.... Even the economic and fiscal update suggests it could rise by 2025 to 60%, which is starting to get very...and that's just at the federal level, never mind the provincial level.
Of course, you mentioned our household and corporate debt on top of that, but leaving that aside for a moment, we will get to a point where a highly indebted country may find all of a sudden that international investors are worried about holding that debt, and that could cause credit spreads to increase and interest rates to rise much more quickly than we expect.
So, yes, I think the threat is there, and the threat will become apparent over the next five years, especially if we repeat the period 1976 to 1985, roughly, when we ran very large primary deficits where we not only didn't cover any interest expense, but didn't cover our program expenditures. My biggest fear is that we're going to get into that.
