Yes. I'll stop you there, because I don't have much time.
I guess what I'm trying to say is you could see productivity go up in the oil patch—forgetting about the price of oil—yet it's a mature industry, and that's not where the innovation of tomorrow is going to come from. Innovation is what drives productivity as well.
There's been an idea bandied about that the fuel charge, the price on carbon at the pump, is somehow harming our economic productivity. What do you think about that argument?
