Right.
I was rather surprised by something at a mining association meeting the other day. There was somebody from the oil sands, and we were talking about future costs of fuel. He said it wasn't in the best interests of the oil sands to see the price per barrel continue to increase exponentially, that there's a point of diminishing returns.
Could you explain in economic terms why there would be a point for the oil sands companies at which they wouldn't want the price per barrel to increase that steeply?
