Capitalism depends on proper competition to function “properly”. So of course the goal of every company is to reduce competition so that they can raise prices to infinity.
Loblaw’s still has competition, but it is not what it should be. There are a small number of big chains that don’t have proper competition in their best interests. If you live in a big city you likely have a few real options but often not really.
The capitalist’s answer to this is applying regulation since it has been required to prevent monopolistic behaviour. Or we can ditch capitalism as the model for our society. Or more likely both, one as a short term fix and another for the longer term.
