Free trade raises incomes. Unfortunately it doesn't raise average incomes. The vast majority of the benefit goes to the 0.01%.

Our manufacturing capacity has been decimated and now our largest companies are being sold off to China. Does anyone actually see a good end in this for the average Canadian. If so perhaps they can explain how it will be good for us when all our manufacturing has been eliminated and our largest companies are all owned by China? 
What will be giving us prosperous lives with dignity then?
