not sure you actually take home half of what you make or that after tax you pay in taxes have of what you earn.  Are you talking about the marginal rate you pay on the first dollar over the highest tax bracket?  Or are you counting CPP contributions as a reduction in income and not taking into account it is future income (and a current deduction against income)?  Not sure what kind of services you expect to get from government or its contractors with less revenue.  Usually when you pay less you get less quality in the open market, why think service quality and speed will stay the same when government reduces ?
