Maybe I can provide the quick answers to that. This is very true, except that according to the Bank of Canada, we're already close to potential GDP. Domestic demand, personal consumption, if you will, is not low by any account; it's very high, it's sustained, so we don't see tax cuts at the personal level as helping much as far as economic expansion goes.
Regarding corporate tax cuts, we've had record productivity for years. This is probably likely to go down, but as we were saying, this has not brought in the investment you could have expected.
