Using my family as an example:
My brother, with a small business, took all the retained earnings from his company in 2015 (when taxes were hiked in AB and federally). Now working with about a third the staff and winding the company down.
My sister, with a medical corporation, who has her own practice with 5 other doctor's is now (with these tax changes) going to close it down and work at a walk-in clinic a few days a week.
I have moved to a 0.8 and no longer sell any stocks for capital gains.
Lot's of people adjust their behavior due to very poorly thought out tax changes.  The government would have had significantly higher tax revenue from our family if they had left the rates where they were.  Now instead of being the hated 1% we all are going to get the maximum "middle class" tax break.
