For decades now the right wing in Alberta, which has been in control of the province for that whole time, has made no bones about not giving a damn about the rest of the country. They've been very forthright about it--firewalls, letting the Eastern bastards (and incidentally any stray non-Albertan Western bastards) freeze in the dark, all that.
So now we have Mulcair talking about Albertan oil causing Dutch disease for the rest of Canada, which it clearly does, and suggesting that we need to take measures to defend the country and its non-oil industries from this. And we have British Columbians not wild about a pipeline which will benefit Albertans but impose mainly costs on BC, costs the Albertans won't have to bear or, most likely, even help with in the event of a major spill.
What strikes me as bizarre is the Albertan right's response: Utter shock that other parts of the country would fail to prioritize Albertan interests. They seem amazed at the mean-spiritedness of other parts of the country in failing to cheerfully support Albertan money-making at their expense. Suddenly now because it's for them, the country must pull together; a benefit to Alberta must be seen as a benefit to all. Uh, guys, if you wanted anyone to give a shit about your welfare you might have thought about giving a shit about anyone else's welfare any time in the last thirty years. Really, why should I give a flying fuck whether their oil makes it to market?
