Regulating the wholesale price of gasoline, in other words. There is some intervention there that's possible, I would say. The big danger of regulating at the wholesale level...perhaps you recall electricity regulation in California. Intervention has to be done extremely carefully when you're regulating the price of a commodity; otherwise you will interrupt supply. If, for example, the wholesale price of gasoline in Canada were limited, say, by 10ยข a litre lower than New York or whatever, refiners in Canada, in this free market, would export all their product, unless you again force them--another degree of intervention--to sell fuel in Canada.
All the gophers have to be hit on the head, if you will, if you intervene in one spot.
