While this is true in a macro sense, the Keystone Pipeline itself will not contribute to this scenario in the micro sense as it will divert oil from mid-West refineries, where the final products are NOW being sold to American consumers, to Texas refineries in free-trade zones, the refined products being sold overseas where the prices that can be gotten will be higher and where the owners of the refineries and the various operators will now be able to avoid paying federal taxes due to the loop-holes in the exporting agreement with Canada and the establishment of the free-trade zones.
Don't believe me...look at your OWN MAP and tell me that once phases 3 and 4 are completed that the bulk of the oil will NOT end-up flowing directly to Texas where they'll get more money for each barrel delivered as well as paying less taxes. It's a no-brainer all right, but NOT because the American consumer will benefit from all of this.
