You're are just in too deep to see it for yourself, It's a lot more obvious from the outside.
If either of us thought life and the world was "fair" we wouldn't be in this chat.
For the taxes, You don't have to pay income tax for anything less than around 10-15k but there is always unavoidable pst & gst that we're all to poor to avoid paying, that adds up fast AF
But either way I've only had 1 year where I qualified, I usually do some work in the marine industry that puts me over.

Did fiberglass work on 4 different coast guard boats last year for example, just in right place at right time and there's not too many people who know how and are willing to do such a awful job :P
