Thanks very much, Mr. Chair.
Thanks to all of our witnesses. I'm going to endeavour to get through all four because you have all brought a lot of very important things to bear, so I'd ask you to be relatively brief, at 45 to 50 seconds each.
I'll start with Ms. Tiessen. Thank you very much for being so eloquent about the importance of social infrastructure, pharmacare, child care. We know that for every buck we spend on childcare we get $6 back in economic stimulus.
Isn't it important as well to take care of the revenue side? I'm thinking of a wealth tax and an excess profits tax like we had in the second world war, which you referenced, cracking down on overseas tax havens that cost us $25 billion a year, and making the big web giant companies actually pay corporate income tax so that we have the wherewithal to make these investments and to build back better, as you stated so eloquently.
