So what? What about the grocery market? What does that have to do with the price of butter? In the US it's also consolidating into a few giant incumbents. Do I get to blame that on government regulation, too? Which regulation? Again, I understand why Canada has an uncompetitive telecom, banking, and airline sector. But exactly what government intervention do you think is responsible for Nordstrom and Target failing to succeed in it? What intervention and regulation uniquely and unfairly advantages retail incumbents? Please be specific.
