Thank you.
Professor Milligan, I want to come back briefly to what I guess we've been tied up about--that is, your comment about boutique tax credits, that environmental taxes are good and boutique tax credits bad. But then you expanded on that a little bit and said that one of the other things that could be done is spending money, versus creating a tax credit to encourage a behaviour.
As a Conservative, I actually look at it the other way. If I look at public transit, for example, I would rather encourage people to ride public transit and have the transit system become economic, and actually be able to provide for itself, than the other way, which is to pour money into a system and have a whole bunch of empty buses with nobody riding in them.
Do you see how that might be a better approach—which is where the government has gone with it?
