So Alberta has higher incomes and therefore contributes more tax revenue per person.   Fair enough.   People there are generous and don't mind helping other provinces.   The west was built on helping your neighbor.

What Albertans don't like is to not receive help when it's needed in return.  The economy tanked 3 years ago now and Alberta is still a huge net equalization payer.   Quebec, always a net receiver with generous public programs, gloats when large projects like Energy East Pipeline that would benefit their own province are stopped.   Carbon taxes also hurt Alberta's economy, while the fuel burners from other provinces pat themselves on the back that they're saving the planet.  Albertans expect a level playing field.   Big industries in other provinces are favoured over Alberta energy.   Logging for example is a hill to die on in free trade with the US, as is Bombardier's messed up business.   Pipelines that enable Canada to sell product at reasonable prices, not so much.
