100% Agree, I thankfully have a local grocery store close to me so I can avoid the big 3, but this isn't a realistic option for everyone. I'm hesitant to just buy online for things like produce as my experience with them has been mediocre (I haven't tried costco though).
This really isn't a problem the everyday Canadian can fix without the government stepping in and breaking up the monopoly of Loblaws, Sobey's and Metro.
I'd love to see a future Canada where there was more local grocery chains, with the same access to product that the big three have. Also would be great if they were closer to where people lives so people wouldn't feel like the need to drive to get their groceries.
I think he's just a capitalist banker with agenda to push capitalist friendly policies but in the context of how he compares it to rules based order (a potentially good thing) I don't think this is what he meant. He says we pretend we have rules based order because it was a good thing even though we know at heart that strong powers can act outside the rules. The shop owners pretend the workers are united (a good thing) even though they know the government is corrupt and does not support the workers.
