Ok, I'll take that bait. 

1) "he" doesn't pay less in tax than you I am willing to bet

2) Lifetime capital gains exemption is rarely used in medical practices.  Do you think a new grad is going to buy a medical practice for 3million dollars when then can just start their own?

3) Income "sprinkling" are dividends paid to shareholders, a major principle of how corporation work.  You can't if you don't own a corporation.  I'd be fine with government not allowing professional corps to have family members as shareholders, but provinces gave them this instead of a fee increase, likely the tax payer will be on the hook one way or the other eventually, just a question of whether it'll come from federal or provincial pot.   

Note that you can sprinkle your pension to your spouse, which represents a significant portion of the "pay package" given to government employees.
