Revenue from personal income tax is not that much. More like about 20%. Corporate is about a third of that.
More like a quarter …
Here are some stats (2009 latest)
http://www.statcan.gc.ca/tables-tableaux/sum-som/l01/cst01/govt01a-eng.htm
Total revenues $585,799 (million)
Personal Income Tax: $189,222
Social insurance taxes: $35,404
GST: $53,625
Corporate Income Tax: $50,277
I'll bet the proportion for succeeding years is even more skewed towards citizens and away from business (or so economists have been warning us).
Income tax is over 30% but add on social insurance, health premiums and taxes that are business deductions and/or are passed directly onto consumers like GST, gasoline, import duties, liquor, and you are easily over 50% for personal taxes.
I do understand that businesses do contribute in other ways, but not when people start becoming a profit center and nothing else.
