Kevin Page, the ex Parliamentary Budget Officer would disagree with you.  His 2012 study said the average value of wages, pensions and other benefits in the federal public sector equaled over $114,000/year at that time while base wages in the private sector amounted to about $55,000 (excluding CPP and EI).  Considering 80% of private sector workers no longer have an employer pension plan of any type I question your numbers and source.
