That's exactly what you're saying when you refer to their share of the costs
No. I'm not. I'm saying that there is value to this resource and giving it away for less than its true value is cheating the owners of that resource. I don't know how you can make a statement like that, in your own words "share" is a non quantifiable term. Oil corporations will be in Alberta as long as there's money to be made, and for all their whining about how hard done by they are, I sure don't see any of them packing up and leaving.
As I've said already, they were given a pretty sweet deal with the so-called "Alberta Advantage" for a long time. The unwritten deal there was that the consideration would come back to Albertans in the form of well-paying jobs and tax revenue. They aren't holding up their end of the bargain, why should they still get the breaks?
