Country: Canada
Corporations have used inflation as a cover to raise prices further than necessary, making the situation worse . Its very clear, its the only explanation for increased profits margins.
Eg.
Many things can impact profit and gross margins, chiefly sales mix. In Canada, many of the large grocers also own other retail brands eg, Loblaw owning Shoppers Drugmart - with the infusion of additional disposable income from stimulus, people have had money to buy lots of stuff which in turn have been higher margin products. There's zero evidence that margins have increased due to "corporate greed".
