The provinces exist on flip sides of the very same coin; they are each others' dark twins, and Alberta seeks mostly to emulate its French sibling.
Alberta wouldn't be so negative on equalization if the receiving provinces would make decisions to expand their own economic development. Perhaps introduce more business friendly policies and perhaps encourage a stronger work ethic. The eastern provinces are seen as thinking they are too good for resource development (such as oil and gas) but more than happy to take money taxed from those industries.
Um. I don't want to say that "Alberta doesn't hate Quebec" is wishful thinking, exactly. But I'd suggest that there's a certain amount of resentment of Quebec in Alberta. Maybe even quite a lot, depending on how the economy is doing. This is unsurprising; there's similar tensions between northern and southern Italy.
