It is not "greedy politicians" but voters who like being bribed with their own or borrowed money - to provide "FREE" social services ( education, health care, roads, policing  .... ).

Secondly - never mind just the income tax - please add all the other taxes from HST, PST, municipal, surcharges, user fees, hidden taxes ( gasoline, corporate, capital gains .... ) The final tax levels are scary and a severe limit on our democratic freedoms.
