Thanks, Mr. Julian, for the question.
Certainly, the tax system can play the role of equalizing or creating a more equal society in an after-tax sense, which is to say taking that money and redistributing it, but also restricting the maximum gains you get at the top end.
In terms of raising the revenue, of course, what this does is it provides us with fiscal room for additional programs. For instance, if we wanted to further expand the child care program or provide much better standards of long-term care from new transfers to the provinces, this is the sort of thing that would give the federal government more flexibility in doing so.
The present federal government's take of the Canadian economy in terms of revenue to GDP is relatively low. It has been much higher in the past. We're nowhere near all-time highs in the revenue take on either the revenue side or the expenditure side of the federal government. The points that you mention about a wealth tax or an excess profits tax are additional things that I think are worth examining in the context of COVID-19. That's in addition to other measures—for instance, some way in the short term of clamping down on profit-shifting as we wait for the BEPS committees at the OECD to work through international proposals on how we do that in a more coordinated way.
