The good professor omits one important statistic, that the top 1% also pay a hugely disproportionate amount of   all income taxes.  IIRC the top 10% pay 50% of the taxes.  His proposals would result in lower tax revenue after legal means to avoid taxes are undertaken by those who can afford professional tax advice, likely from his own students.
I find it interesting that even if the government imposed the new "revenue tools" the assumed increased revenue would only fund one month of Trudeau induced deficits.
