I thank you all for being here. I will start with a question for Mr. Davies.
Even though it differed somewhat from what we normally see, I found your brief very interesting. It shows a very humanistic approach and brings us back to an inescapable fact: the economic model is not an end in itself. The purpose of the economic system that we are building is to help society. It is not an end, a goal in itself. That's very interesting.
I also appreciated the fact that you brought forward some original proposals: how the economic system could be humanized through simple changes in the tax system. You suggest, among other things, that companies should not be allowed to claim as tax deductions their advertising or lobbying expenditures.
You also mentioned the Tobin tax on capital movement. I have been interested in such a tax for some time now. Could you explain to committee members how this tax proposal—which has been in the air for a while—is working, and tell us what its benefits would be?
