I have to say thank you very much, Chairman, for this kindness, and to all my colleagues. The witnesses were so interesting today.
My question is for Dr. Cochrane.
Given that we need to have, I believe, new sources of revenue to ensure that, as the economy picks up post-pandemic, we're able to bring in social programs that address the inequities that have become so apparent through COVID, given the choice, if you had to pick one measure, which one do you think you would most like to see in Chrystia Freeland's next budget? Is it the wealth tax? Is it the excess profits tax?
