In a recent debate on the pages of the National Post many Albertans might have missed, two economists, Rhys Kesselman from Simon Fraser University, and Jack Mintz from the University of Calgary, sparred over the most desirable tax mix for Alberta. Kesselman wanted Albertas single income tax rate replaced with cascading tax brackets, and structured to ensure higher overall taxes. Mintz advocated a sales tax but with the caveat that it be revenue neutral, i.e., some other tax should be lowered in exchange.
