No you do not
That is a separate issue all together.
Incremental benefits for Canadians relative to the US should be considered , however as a separate exercise
1. The relative value each Canadian receives from these benefits will vary & vary a lot
2. taxes are paid from the day you start to spend until after you die, the child benefit pays patents maybe 18 to 30 years for multi-child familes , zero if you don't have kids or if your kids are over 18 already.
a) The benefits received will vary significantly across Canadians . You would need to calculate a weighted across the the taxpaying population, o for those with no kids or grown kids and 1 each for kid for tax paying parents with kids
b) it is not a ongoing benefit , taxes are never ending. Parents will only receive these benefits for maybe 25% to 40% of their tax paying years, 0% for those taxpayers without kids or grown kids
3. Other non cash benefits from Government ie health Care, subsidies also vary depending upon usage.
There is no way you can accurately calculate average or marginal utility from these benefits, so adding them to precise tax burden calculations produces results which are not precise
Comparing imprecise tax burdens is a useless exercise and misleading
In addition any estimate of the value of the non cash benefits is just that an estimate and is subject to misinterpretation. in your case misinformation and exaggeration
Is there benefit? sure, that is obvious, however as pointed out already each of us must determine if we the value get for the incremental tax paid is justified
However the big reason is
you will get it wrong.
Sadly we have witnessed your (lack of) math skills
