So then how does the math work out in Canada presuming you had zero side affects at what % your you tax the high income earners? Their 60 billion in income is already taxed at 47% marginal rate.
75% would net us another 15 billion per year. As an alternative we could tax 20 million tax payers $700 per year more to raise and equal amount of money.

But the real problem is taxation as a % of GDP. Sweden collects significantly more tax dollars over all

So if you look at the above link the top tax rates in the Nordic countries start at 1.3 -1.6 times average incomes so somewhere above 75-80k the marginal rate would be 53%.
Taxing people in the 25% not the .1% is the issue.
