The basic argument goes like this: A barrel of oil sands crude currently trades at a lower price than other global oil benchmarks. That price gap means Canadians are losing money on every barrel sold. Access to world markets will fetch higher prices, elevating our collective prosperity. It's a persuasive story, tickling the part of the brain associated with loss aversion. No one wants to bleed money day after day. At the same time it paints a picture of one nation, our fortunes rising and falling in unity. It's good politics. But the reality is more complex.
